[QUOTE=dan stark;375186]Extra tie outs may help, but you would have to have something that clipped to the tarp. There may be a piece of equipment out there that does that. Kinda like a spring loaded clothes pin, but better.

====> The is! Google "Grip Clips". I carry a bag of em! Can put them anyplace on fabric, take em off afterwards. They provide tie-outs anyplace.
