Yep. I feel it twice; out of my pocketbook AND my wife constantly reminding me to cut down on miles. I bike to work every day which might help a little (unless there’s snow on the roads).
I always carpool w/ backpacking trips and my groups vary between 3-6 unless we’re with scouts.

I remember NiytOwl bringing this up a couple years ago: http://www.backpacking.net/forums/showth...rev=#Post107905

Wow! Long link. Hope it works.
