Re: Shelter
I have read this many times, and wondered on just such occasions about the whole 'shelter' thing.
As my fellow commentards have already noted, I'm sure many of us regularly spend more than 3 hours, out and about, with no ill effects. Even in more extreme situations, I remember this one time, when i was doing some backpacking, arriving in Nice a bit late in the day, all the hostels were either full or not taking any more in for the night, so we slept on the beach, no sleeping bags, just jumpers as covers and bags as pillows. Uncomfortable due to it being a pebble beach, but i survived. (at least, i think i did)
