When you stare at a barefooter’s filthy soles, would you rather they be dirty from street dirt (grime, oil, dust) or nature trash (grass, stains, leaves, mud)? Preferences? Voting and bitching may now begin!
i don't think i've ever stared at a barefooter's filthy soles before, but i would think nature stains would generally be preferable. with the exception of poop.
C'mon, now....you ain't lived until you've got some air from that dog bomb or bear scat you just stepped in....
