dude, my calves were not hurting. and my arms only hurt on that first overhanging bulge climb that scot'teryx and sergio tr'ed. (talk about pumpy!!!) all i know, though, is i want more steeper waterfall ice. i got some pics, too, but will wait until i finish the roll to get them developed. oh, and it wasn't *that* cold. nunatak kobuk mountain jackets (and warm tent buddies) rule!
