For the record:
I am currently sitting in a room with a space heater on wearing full thermal underwear (with an undershirt), socks (I wish they were thermal) Thai-style fishing pants and a large wool-style hooded pull-over...with a 64oz Boathouse Farms juice bottle full of hot water under my top two layers.
The thermometer says 49...and thats up 3 since I first checked this morning.
