I have seen "pads" made of both concrete and wood and granted, the concrete ones offer no insulation value what so ever. You can freeze your _ _ _ off on one of the concrete pads. The wood ones are a little better if they are close to the ground but I would still rather be in a tent right down on the ground or swinging the night away in my hammock....sabre11004 goodjob
