while i don't mind the cold at all as long as there's no wind to go along with it.........I'm gonna have to side with Gordon on this. regardless how hot you get, a few sips of water and 5 min under a shade tent you're cooled off for the most part but once you get cold you're cold all day. i can fly with no problems well below freezing but when it gets below the low 40s with wind my hands don't do what i tell them to do so the flying stops.
