We went camping on Saturday night. Live at 5800 above sea level (denver) but traveled up into the mountains to about 8200 feet and camped out. Fire was lovely, it was cold, in the 20's. I was chilled but okay until it came time to step into the tent and sleep. Misearble cold night... waiting for the sun to rise so we could come back home. Anyone else do "winter" camp outs?
