I like to be connected firmly to the earth. Love having my roots in dirt. Or wherever even on rocks. I actually once slept on glass. Set up exhausted after dark and when I broke camp in the morning found that the spot years ago was obviously a garbage spot for an abandoned house nearby. New green grass had grown over and it looked good to me in the moon light. The glass edges were not too sharp, had been dulled down in time. I had a Thermarest air pad that was not punctured. I have a hammock in the back yard and love it too but actually prefer the ground. I guess a hammock does get you above the night sniffers but you miss rolling over and sleeping face down.
