Okay, I'm sure there's a place for the idea of taking off a hat, and shirt, and throwing it in a pack while hiking. Wouldn't it be a good time to stop and enjoy your surroundings (tip from a previous week)? I think it's a neat tip, and could move a UL'er from Nerd to cool (okay, maybe it would take more than one cool move) but I can't think of a time I'd NEED to not stop to take off a shirt and stuff it in a backpack.
Warning, what follows is potentially thread jacking, proceed at your own risk:
Mike, the book is outstanding. I'm going to admit something. You have tips about natural toilet paper. Towards the beginning to the tip you talk about being disappointed with UL'ers that go and use TP. When I first read this I got indignant. Who are you to say... Long story short. You got me. I realized it's a book of ideas (excellent ones) not a rule book. I'll stick with TP (maybe only for now, who knows). Point being, thank you for expanding my mental tool belt so that I can make do in the woods. The day may come that I try it without TP.
Until then you'll just have to be happy knowing my BPW dropped from 47lbs (all that excellent military training), to just over 8 (retraining). My weight dropped from over 200 to under 180. Your books got me back on the trail, living. I look forward to even one night out under the stars. It's the best sleep I get.
Before anyone goes on about, "not a real UL'er if you use TP..", I'd like to point something out. When I go out, I don't bring the following: anything that requires electricity to operate (GPS, kindle, cell phone, radio, etc). In order to do it right to me, I have to leave the digital world behind. I have to. No watch. I militantly do not want to know what time it is or even what day it is.
I do bring a camera (Rollei B35). It is a fully mechanical film camera. Yes, film. I may bring a book. Without a flash light I read by the glow of light sticks, firelight, or during the day. This won't work for some/everyone, but it works for me.
