funny that this thread came up. I was on my morning walk a couple of days ago and watching the town wake up, reminded me of the days I lived out of a pack or off a bike. Squirming out of under a tree, back amongst the living.
today with all the great light weight equipment around, a bit of forethought and a little experience, there is no reason to be uncomfortable or wet. It was a beautiful morning and I couldn't help think what a nice feeling it would be to just strap on a pack and walk, no maintenance or mechanical gremlins to worry about other then a new pair of shoes once in a while. There is something liberating about that.
I always migrated to warm climates when backpacking, it just doesn't make sense to me otherwise, unless you have to or you are trying to prove something.
