Congrats on post #3,000, Jim! And thank you for the kind words, although I don't consider myself that tough! For one thing, I need a really comfortable air mattress, and every year I need a little more cushioning. I suspect that my 2.5" thick POE insulated air mat is going to get too thin in another year or two! I also need a lot of warmth at night, so none of this trying to endure in a 30* F bag with extra clothing! That's why my base weight runs 4-5 lbs. more than those UL folks over at Backpacking Light! (Of course I include a number of things they leave out, like fishing tackle and a camera!)
