The biggest problem is that after they have gone backpacking with me just once, they realize how uncomfortable camping is with a tent (or how comfortable I look in a hammock) and then don't really want to come again. Mostly just my relatives are like that, but if I provide more comfort for a friend that would definitely help my odds of getting them to join me in the mountains. I don't know if I would bother to buy them a nice lightweight tarp since even 9x9's aren't cheap.
Auction? I would have to bid on something...
