This is often called a "Wood's valve" (or perhaps, Woods valve).  Old
Dunlop patch kits came with a short section of rubber tubing for
repairing such valves.  In addition, early Japanese sew-ups (tubulars)
came with Wood's valve adapters.  These valves are virtually nonexistant
in North America.

As for and end to auto subsidies- take a look at how much mass transit

As a not-so-cheery confirmation of this, I happened upon an accident scene
on Skyline (SF. Peninsula) where a motorcycle rider got hit head on by a
van (the motorcycle's fault I think). The rider got blown right out of his
calf-high leather boots. Needless to say, the paramedics at the scene
didn't have much to do except scrape the guy off the road.... He was
wearing a helmet too...

He could ignore air resistance.  The timing was not that accurate, and both
objects were quite dense.

Bikers cannot ignore air resistance.  They are racing, and would care about a
small difference.  They're also on a slope, which evvectively reduces the
cyclists' density.

Soapbox derby racers routinely make sure their car weighs the maximum allowed.

	This bike is less than three-month old and I am selling it
because I am moving away soon...  It is one of the best Giant Cross/AFS
Series (Innova is right next to the top of the line-- Prodigy).

	-Giant Cross Design Cro-Moly Frame and Fork
	-21 Speed Shimano 200GS Component Group
	-STI Rapidfire Shifters
	-Shimano Cross Cantilevers

	This is a great bike!  You can ride it fast on the road or going
up treacherous hills.  No Problem.  The color is Shadow Web Metallic
Mulberry with Purple Ice.  Extremely Cool!

	I bought it on sale for $350.00.  Usually it costs close to
$400.  I am selling it today for $300, OBO.  It will be best if the
buyer can pick up the bike from me. I will be in Schenectady (near
Albany, NY) until the end of August, NYC from beginning of September to
September 10th, Cambridge, MA after that.  Therefore, you can pick up
the bike from me in any of the above three places.

Subject: Re: MYTH or FACT:  Do bicycle helmets wear out from age?
Organization: Cray Research, Inc.
Date: 18 Aug 92 13:48:22 CDT

Based on one data point, which I will describe below, I believe:

1) Foam hardens with age
2) UV exposure is not responsible

1) Foam hardens with age - This spring I dug a fingernail into the foam on my
two helmets, a 6 year old Bell V1 Pro and a 3 year old LT. The foam in the LT
was slightly springy. That is, it would give a little and I could leave an
imprint. The foam in the V1 Pro was hard. Rock hard. Maybe the V1 Pro has
more dense foam, but I can't believe it could ever have passed the ANSI test
in the condition it was in.

2) UV exposure is not responsible - Actually I poked the V1 Pro all over. There
is a gradient to the amount of UV exposure the foam has seen, but there did
not seem to be any gradient to the hardness of the foam. OK you say, this is
not a carefully measured experiment. You're right, I answer, but if the UV
theory is true, then the foam under the shell should have been in new
condition, seeing as that foam hasn't seen any UV exposure at all unless Bell
made the thing outside. Yet when I yanked the liner apart from the shell,
the foam there was as hard as the rest.

This is only one data point, not quantified, not even repeatable since the V1
Pro is now resting peacefully in a landfill, releasing CFCs and destroying
ozone. But the motorcycle helmet studies showing reduced compressability in
older foam would not seem to implicate UV. UV does not penetrate the shell,
and humans do not emit it, at least not as far as I know. Even if you left
your helmet sit in the sun, I wouldn't think UV would penetrate deep enough
to affect the foam beyond an outer crust.

If there are any chemists that can tell me how and where the above anaylsis
is wrong, I'll listen. But until then I absolve UV of any responsibility
in the hardening of my helmet foam.

Actually, not necessarily so.
The catch is where you say "through no fault of his own".

The lawyers are arguing (and winning) saying that, meerly by the fact
that the plaintif was not wearing seatbelts, the plaintif contributed
to the severity of the injuries. They have been able to attach fault
to what otherwise would be considered a completely faultless situation.

For automobiles it has been successfully demonstrated repeatedly to
the extent that it has now become somewhat standardized, that auto
drivers and passengers sustain xx% fewer injuries if they are wearing
seatbelts compared to those who do not wear seatbelts. It has been
proven with hard statistical data. They are armed with accident
reports citing same makes of vehicles, sames speeds, etc. where some
accidents' participants were wearing seatbelts and others weren't. They
get the data from the insurance companies who have a vested interest
in finding out in great detail where their money goes and why.

The lawyers who argue for reduced settlements simply trot out the
statistics then charge the plaintif with "contributory negligence".
And they win. Can you imagine being stuck with 2/5 of a $120,000
hospital bill? It happens.

DISCLAIMER: I'm not a lawyer and I can't remember the exact
percentages (e.g. 2/5).

I was told this by a twenty year police veteran who is a friend (i.e.
was not trying to 'sell' me on seatbelts). He spends a lot of time in
court and has had to testify in cases where this has been an issue.
This issue made a profound impression on him.

The AVG algorithm (sp?) use only hours, minutes and 10 seconds - not the

Hello,

I've finally been driven to post my opinion by Mark G. Salyzyn's 
account of a pedestrian-caused accident.  Why are bike paths shared????
A bike path is for bikes.  A sidewalk is for pedestrians.  Period.
I use the Lachine Canal and de la Verendrye (aka LaSalle Aqueduct) 
bike paths daily to get to work.  There are pedestrians on these
paths, but they usually walk against traffic and step out of the
way onto the grass when they see you coming.  The ones that don't get buzzed or
yelled at.  I can usually maintain between 35 and 40 kph on these
paths, depending on the time of day.  If (slow) bike traffic is heavy,
prudence requires that you slow down and wait for opportunities to
pass, just as when driving on a two lane highway.  But pedestrians?
Relatively speaking, they're standing still.  Send them to the 
sidewalks.

Conversely, I have to go about half a block against heavy traffic on a 
divided avenue every day to get to work.  Because of the configuration
of the roads in that area (near the MNI), it would add several km
to go around.  So, I WALK my bike on the sidewalk, as per the law.
This makes sense since it is a busy pedestrial area as well.

[Discusses different kinds of falls with toe-straps and clipless pedals.  
Asks aboud RAD fit-kit for SPD and Time.]

I've had a set of Shimano SPD pedals (Deore XT or M737) on my bike for a few  
months. I've fallen three times. All when I was tired and something else  
went wrong. The first two happened on a ride a few days after I got the  
pedals.

There are indeed RAD fixtures available for SPD cleats. For those not  
familiar with RAD (Radial Alignment Device), its basically a box-like pedal  
mechanism which can rotate freely in the horizontal plane. There is a rod  
sticking out that stays perpendicular to the crank and another rod that  
stays perpendicular to the box. On top of the box, an aluminum cleat fixture  
gets mounted which has a little cut-out to hold the particular kind of cleat  
you have. They strap your feet down onto the cleat fixture and you pedal  
normally. The person doing the adjustment watches the rods and adjusts the  
cleats until they stay lined up and don't move with respect to each other as  
you pedal. Few stores have the SPD cleat fixture now, but I expect that will  
change since SPD is on the rise.

A friend of mine and I mounted the cleats on my shoes and then adjusted them  
by feel. I rode that way for about a week and then had a RAD fitting done.  
The store only charged me $10 for the adjustment since we had already gotten  
it pretty close. ($235 normally though its free if you buy your cleats and  
shoes at that store.) I haven't had any problems except for a week ago  
Sunday, I rode 66 miles (550 feet of climbing) in a century before bailing  
out due to knee pain. (Which may not have anything to do with the SPD  
pedals. My knee still doesn't feel normal after a week of not riding and I  
will have the adjustment checked if I continue having problems.)

Right, so you were wrong since you suggested that Amtrak has been able
to achieve only 55% in your original posting.  I quote you:

	Consistently they [Amtrak] have managed to get ridership up
	to the point of paying approximately 55% of their expenses.

How so?  The NRPC (Amtrak) 1990 Annual Report states on page 14:
"passenger-related revenues--derived from the sale of passenger tickets
and on-board services--make up approximately 71 percent of Amtrak's
revenue base".  So the American taxpayer can at best only be paying
for about 29% of Amtrak's revenue base in the form of a subsidy.
