I have found that sleeping on any kind of slope results in a night of slumber-sledding. That is, the ground cloth(plastic, tyvec, etc.) is slippery, sleeping pads are slippery, nylon bags or bivy sacs are slippery and together it seems to be a problem. How do people get around this?
Yes, I know, "Find a flat spot to sleep!" But we all know that isn't always possible. Thoughts?!?!
