It certainly warms things up!
On a down note, my BBO stuff sack disappeared over night. I think it might have blown into the river I camped near. BUMMER!
Thanks for the info Big D. How much of a gap is there in the BBO with the head end loose? Sorry about your stuff sack. It's so small it would be hard to find if it went very far.
