This isn't as clear cut of idea as it may seem. <img src="/forums/images/graemlins/smirk.gif" alt="" />There is a NEW concept of "tent footprint" which many have accepted and many do not. I personally NEVER put anything under my tent because it almost always act as a resevoir and funnels water under your tent where it stays on top of a tarp and you will be wetter than with no tarp. If you think you really need something, use a very thin layer of plastic inside your tent against the floor and put your gear on top of it. The old fashioned ground cloth was made of canvas and didnot hold water, of course tents had no floors then - thus you slept on the ground cloth.
