We went tent camping last week, first time in a while. Waaayyyyy too warm for our 20 and zero degree mummy bags, so we just used one of my old poncho liners. Perfect for the low 50's (give or take a few degrees) nights here in the Pacific NW. Along with a little snuggling of course.

Side note: my old (bought in 'bout '88 or 89) little dome tent finally blew out a zipper. Gonna have to look for a suitable replacement now. Lotsa memories in that tent...
