I'm thinking of doing the Wonderland Trail again for the fifth time (it's been some years since I've done it), and I'm considering just using a couple of Polarguard coats (one WIld Things and one MontBell) along with a bivy bag and a sleeping pad and just skipping the sleeping bag. I also plan on leaving the stove, pots, etc. behind and just using cold food, and doing the whole thing in four days; five at the most. Any thoughts on this?
