There's a good article in the September 1992 issue of _DIVE Training_, p.46, on
this very subject; however, there's too much information to reprint here.

Hi scott,
I've done alot of air/train travel with tanks. The tank must be empty and 
the valve removed. The concern (aside from smuggling) is a vessel under 
high pressure in a hostile environment is very unkind. 
All else, contact your air carrier for an official ruling. 
Unless you/they have some really custom rig. I'd grab a few tanks 
at the junp in point and enjoy the convenience and lack of hassle of
dragging 40lb+ around.

...and may all your tiny bubbles be in the champagne!!!

Call Seaquatics in Midland.  The water is Saginaw Bay is way to shallow
and murky to dive in.  From the tip of the Thumb east, there is a bottom-
land preserve of shipwrecks.  This visibility in that part of Lake Huron
is pretty good.  You may find a group of divers going there
or maybe Seaquatics can help put you in touch.  There used to be a small
low budget kind of dive shop in Bay City, but I don't know if it is still 
there.  About 60 miles northwest of Bay City is Higgins Lake (I think, 
it's been a while and there are two lakes just a few miles apart there...
anyway) which is as deep as 135 feet in places, very clear water (the
visibility will knock the fins right off your feet for inland water) and
a few artificial reefs, sunken cabin cruisers and such reachable from
shore.  This stuff is in between 30 and 60 feet of water.  Call The
Scuba Shack in Higgins Lake.

	Sorry I saw this too late to help you out with your weekend. 

	The only dive shop I know about is Diving Discovery in Bolton Landing on
Lake George.  (It's on Rt. 9 right across from the town park.)  I saw a sign 
once last year with a dive flag on it at a hotel on Rt. 9 farther up Lake George
but don't remember which one or exactly where it was.

	The water in Lake George is COLD.  The water temp this year at the 
surface was about 6 degrees below the average.  Usually you hit the 
thermocline at about 40 feet.  This year it was about 30 feet.  The visibility
is so-so.  I'd say maybe 40 feet at best.  The visibility gets worse the
farther south you go because of increased boat traffic.

	Sights-wise, we usually went up to around the narrows.  One exception is 
a dive around Diamond Island.  If you go off the north-east shore, you can
find some good size crystals.  It's pretty shallow and I'm not into crystals
but it was a nice shallow dive.

	A lot of the bottom is just milfoil (sp?) and silt.  If you go up
around the narrows and dive around the cliffs, there are some interesting
rock formations and some fish like to hang out there.

	If you know anything about the history of the lake, there were a few
Revolutionary War battles and some other boats sunk in various places.  We
had a dive master from Diving Discovery take us to some nice wreaks but I
couldn't get you back and he didn't want to publish the information so that
he has good places to dive.  We've done some shallow diving around different
islands.  Be sure to drag a dive flag and be careful coming up.  The boaters
on the lake are CRAZY.  Many don't know the rules and wouldn't abide by them
if they did.  Lots are drinking heavily on the weekends.  It gets better the
farther north you go because there are fewer boats.

	If you have a depth finder, you can find ledges around the lake that
make interesting diving.  Diving Discovery does run charters if you want
someone to take you around.  I don't know how much they are operating this
time of year but they are active on the weekeds because a lot of check out
dives from the area are done there.

	It's not great diving but when it's all you've got close by .......

I bought something similar to that when Ikelite put the disk cameras in a 
"waterproof" case.  The case kept the water out but on the first use the 
camera failed.  Granted it was a cheap $30 disk camera but I thought Ikelite
should make good on it.  I never got any satisfaction from Ikelite.  The case
and broken camera are sitting in my closet on a shelf and it will be a cold
day in August when I spend another $120 with Ikelite again.  I would rather 
rent a good camera than to trust my diving pictures to Ikelite.

    I specifically remember reading in either Popular Science or Popular
Mechanics a few years ago about such a device.  It resembled (to me) one
of those rubber icebags, only black, and the user puts his/her mouth to
the opening.  I believe it had to be inflated from the regulator to be
used.  It certainly wasn't for constant use, just for when you have to
get a detailed point across.

    Does anyone know what ever happened to this?

I don't have a moustache, but I tend to keep my mask constantly
"over-pressured" anyway, by blowing out gently through my nose.  It just helps
prevent mask squeeze as you descend, and compensates automatically as you
ascend.  Occassionally I get peeved with the little buzz of bubbles escaping,
and press the mask tight against my face, but the habit is pretty strong now,
and it doesn't do any harm.  It certainly keeps my mask from leaking.

If it is true that using Enriched Air (aka nitrox) is reducing
"asymptomatic DCS" and this explains why some people feel better
after a dive using nitrox than they would have after the same
dive on air, I question whether the DCS is, strictly speaking,
"asymptomatic." Is tiredness just an unrecognized symptom?
It is truely scary to think that we are routinely suffering
unrecognized DCS like that.

Are there long term consequences to such "asymptomatic" DCS?
This would seem to be an extremely strong argument for nitrox.
But why wouldn't just backing off a couple of stops on the tables
give the same benefit, if the well accepted theory of equivalent
air depths is correct? Of course we can't back off a couple of
stops on no-decompression dives.

At what partial pressure of O_2 is it true that your body can't
benefit from more? Obviously it is higher than .21 ATA, or we
wouldn't use pure oxygen for first aid (except possibly for
DCS hits to wash out nitrogen). If it is as high as 1.0 ATA
then the extra O_2 in nitrox may be of some direct benefit
since air only reaches 1.0 ATA PPO_2 at about 130 feet, which
is deeper than most nitrox dives.

Thanks for reminding me to thank Oztotl for 70F spring water.
But what does this 80F to 42F figure mean? Does it assume you are
naked, with no wind or current in either case?

Bill is desperately trying again to minimize the seriousness of DCS.
Face the facts, DCS can and has often caused divers to DIE. When you
get DCS, bubbles form in your tissues and in the blood stream. If a bubble
were to reach the brain before dissolving back into the fluid you get
an embolism. This causes strokes and many other problems. DCS is not
something to be treated lightly. When you discard DCS as a small problem
with little or no threat to life you show your ignorance. Most recreational
divers do not know how dangerous DCS can really be and people like Bill
don't help. When you say that being hit by DCS at 60 feet is virtually
imposible you really show your ignorance. What if the guy made multiply
dives, what if he was on his way up after being down too deep for too 
long. You say that a "fatal DCS hit is unlikely anyway", reguardless of
what you claim to have read, I know profession divers, doctors, and
research scientists who would claim otherwise. I'll take their word
for it and always be prepared. Like you were taught in dive class,
"Plan your Dive and Dive your Plan".

If you are aware of the dangers and avoid them through proper training 
and preparation diving can be an enjoyable sport. If you disreguard what 
experienced people tell you and think that you have nothing to worry about 
then you WILL DIE.

Experince has taught me not to minimize any danger that nature puts
before me. If you are unprepared, anything that can go wrong, will
go wrong.

Always remember: "The greater the pressure, the greater the hazard"

"There are old divers and there are bold divers. 
But there are no old bold divers."

I flew "Aero Cancun" charter from Baltimore to Cancun last January.  I
think the price was about $360 round trip.  For about $50 more they
added a "Aero Cozumel" flight to hook us up between Cancun and Cozumel.
The taxis cannot pick up at the airport in Cancun.  They can
only drop off.  They want you to take the expensive airport cabs to
Cancun and limo/busses to points south.

We paid for the shortest airport cab ride (Club MED, I think) and told 
the driver where we really wanted to go.  He flagged down the cab driving 
behind him, transfered bags, and we got the trip to Playa del Carmen 
for about $40. Or you could just walk past the airport gate and flag 
one down.

To get south real cheap, have the driver drop you at the road and you
can catch the north/south bus for about a dollar.

There are several ferries.  If you are not in a hurry, the slow one
is real cheap.

Of course, we had pretty good vis, too.

I suspect you are correct in that the camera metering was mucked

I've taken my Aladin Pro to a lot of strange places, most of the time I let
