Thanks Duane again, and everyone who had tips.
Wally world has twelve 2 1/2 gallon ziplock bags for 2.98 +tax. I had almost everything except my cloths in one kind of ziplock bag or another. Even though the pack has a bag compartment, I left my slumberjack bag in it's stuff sack and then packed cloths around it. Glad I did it that way as the cloths were dampened, and the bag was nice and dry.
Safe trips all!
