shit man I feel you. I went like a week up at whistler years ago and it was sunny as fuck, and I didn't put on a drop of sunscreen. Needless to say, many sleep deprived nights followed, with full chunks of skin and ear and blood and all that shit a pervasive and painful mess for days and days.
Followed that up with an almost equally bad burn climbin on mt rainier a few years back. Good god that shit hurts.
