I would like to help out on a terrain day. Building and painting terrain is one part of the hobby that I don't have much experience at because I don't have a table at home. But, I agree that having a nice looking terrain setting on a table enhances the gameplay. I think it also helps the stores because when people walk by and see well painted miniatures on a table decorated with well crafted and well painted terrain, then they are likely to show more interest in the game.
