Thanks Gary and Egret.
Monday night was brutally cold (for summer) and I woke up several times shivering. I have been camping in October and not been that cold. So Tuesday night I doubled my clothing: two pairs of socks, my "outdoor" pants with my "sleeping" track pants, and both of my jackets. I still woke up cold a couple of times but it wasn't as bad as Monday. Wednesday it was relatively normal and Thursday I was shedding the extra layers.
