This weekend we will be participating in a Walk For Life. Basically, it is 18 hours of walking a track, with at least one team member on the track at a time. We have a screen tent and a sleeping tent. Unfortunately, the lovely New England weather prediction is for rain and wind in the 50s. Any suggestions for keeping the sleeping tent warm, so that we can at least dry our clothes out? The screen tent might keep us dry, but little else. We won't have electrical service available.
