“Did I tell you about my other trick for staying warm when it’s really cold? I found it out by accident; I can’t even remember who told me. It’s going down to -12 C tonight so I’ll try to do this one later if I can’t get a room.
“You know those plastic packs for warming your hands and your feet, you can get them at the hardware store and other places. You just squeeze them to get them started. When it’s real cold, I try to buy six of them before I get into the sack: 2 for my front pockets of my pants, 2 for the shoulders up in front here, and 2 in your socks for your feet. They go for a pretty reasonable time so it works pretty well.”
