Camping in a freezer

Spent another night camping yesterday, suffered possibly one of the worst nights sleep due to my feet being very cold, along with the rest of my body. I need to huddle into the fetal position to regulate any form of acceptable body temperature but strangely I still really enjoyed myself at my girlfriend's camp-out. She also left for Nepal today with tears in her eyes as she will be away from home for 6 weeks, I will miss her very much.
