... not sure where you are going with that, but usually when im camping, im so tired i could sleep on broken glass... actually i find air mattresses uncomfortable. [/quote]

Thanks for clarifying my motives Joe...some people like to give up all the luxuries of home, lay their sleeping bags on the hard ground and can sleep soundly .  Whether or not it's an air mattress, I just prefer to have some type of padding under my sleeping bag.
