Good tips MNpurple! One that I've found is is I get sweated up on the way in at all, I need to change my socks and t-shirt, then I'm good to go. In the wind it's another story, however, that is just brutal, maybe sit on the ground then. Also, take a little something to munch on, when your body is digesting and you are chewing, you actually warm up quite a bit.
