"I never understood why there is a Chaff thread on a backpacking forum anyway."
Ahhh, but Dave, we need chaff! It's got something for everyone! As I said in some other thread some months ago: "I like chaff. It's interesting, funny, very human, odd, quite intelligent, stupefyingly inane. It's the BPL soaps (only much better than General Hospital!). Or, it's the cheap beer portion of BPL -- a bit of it makes your head feel a little fuzzy, but too much of it and you'll regret it in the morning."
