kinda off the wall, but here's a tip if anybody needs a tarp. You can go to your local outdoor communications (billboards) office (Lamar?) and get the used signage usually for free. They are around 10 mils thick reinforced vinyl. They are variable sizes but most are around 10' x 36'. The actual one I have over my boat right now is the billboard from last years MSU basketball that says PUSH on it. They also make great "slip and slides" for the kids.
