I trick I learned camping at Cape Hatteras is to put rubber bands on the guy ropes. A tight tarp will shed the wind. A loose one will catch the wind and pull looser as well as flap and make too much noise. Rubber bands will store the wind energy during a gust and release it after the gust. Iíve used cut up inner tube for years. My beach setup uses 1.5 to 2 inch wide loops on 10x12ft blue plastic tarp. In the woods Iím using .5 inch wide loops on my sylnylon tarp because I donít want to put too much stress. Doubling parallel makes stiffer, doubling serial makes stretcher. Bungee cords just donít work the same. I havenít found any car/truck inner tubes for years so have been playing with bicycle inner tubes, they are thinner so Iíve cut then .75 in but since the loop is so long the stretch much more. Every camping trip is an experiment with new setup for me.
