Abnrml1,

I've been through that section in very early April. You could have a cold snap I guess, but by the time I got to Erwin (love that stop) I was mostly sleeping on top of my bag, though I was wearing clothes. Trail Days in Damascus are usually pretty warm. If you have a base layer like wool undies, and maybe one of those military surplus sleeping bag covers (usually really cheap) a fleece bag liner would be safe and cheap (and snuggly).

Have a really good trip. That's great hiking country. Best, jcp
