Oregonmouse,

The cooler is kind of a specialty item as it doesn't work under a pack well. I've tried cotton shirts and they dry too quickly. Unless you are near water, there is no place to wet them again. I wouldn't use the cooler except I already had a couple.

I'm down south in Pueblo. About 3 miles from the old Mexican border which used to run along the south end of town.

It's supposed to hit 89 here today which is about 6 weeks early. We should be having frost at night, but haven't had any since early March. Strange weather. It will probably turn into a lot of thunderstorms.
