Example Input: The Seward Highway south of Potters Marsh is essentially a two-lane country road between major urban areas.  A two lane country road with tandem tractor trailers, motorcycles, RVs, pick-ups towing enormous boats, gawking tourists, and Alaskans just trying to get somewhere. The speed variance between these vehicles is dangerous.  Nowhere else in America will you find anything like it. Compound that danger with falling rocks and hazardous winter conditions.  Aggressive traffic enforcement does little to address the fundamental problem that it is a woefully inadequate road for the traffic it receives. The state should be applauded for recognizing the problem. Indeed, let’s straighten and move the road and build all the quarries necessary to do that.
Example Output: No

Example Input: This is exactly how things get ruined for everyone.  Ever wonder why you can't go hang out in nature at night, even though you don't want to start a fire or leave trash behind?  It's because horrible little brats like this came before you and made such a mess that now everything is off limits, has to be routinely patrolled, and ends up becoming private property because it simply costs the city or state too damn much to keep cleaning up after these types of people.  They spoil it for everyone else who simply wants to enjoy nature and leave only footprints in their wake.
Example Output: Yes

Example Input: Saynt----"In a region that has already way overshot its ability to sustain humans into the future,
ME --- Utter nonsense. Under 2% of Oregon is urbanized

Saynt----"Whether we grow up or out, we cannot do so indefinitely into the future.
ME -- Why not? In case you haven't heard, the Earth's fertility rate has been declining for almost 1/2 century. OF course the sleazy green money grubbers don't want you to know this because the need to scare you into sending them money to pretend to solve the (non-)problem.

Furthermore, growth is highly subsidized by taxpayers, and yet it never pays for itself. See: http://www.fodorandassociates.com/rpts_and_pubs.htm
ME Somehow we grew for 150 years without bankruptcy. So this is more bull crap from the anti-growth zealots. Next you'll try to convence us that we should get out of $0.25/passenger-mile cars for $1.00 per mile buses or $1.60 per passenger-mile toy trains. http://www.debunkingportland.com/top10bus.html
