Not any more - when I was in West Yellowstone 2 months ago, they had 4-cycle
snowmobiles stacked like cordwood.  I won't speak for PWC's or outboards.

Thank you for the references re: 2-cycle pollution.  I didn't believe it was
that bad. In fact, from an engineering perspective there's no logical reason
except piss-poor design for it to be that bad.

Walk softly,
Jim
