Whether car camping, hunting, or having a picnic putting up a tarp was the first thing my family did, probably because around here the sun will eat you up. So, we've had everything from canvas to nylon to wally poly. My uncle was in the Air Force and would sometimes string up a parachute for shade. I'm covered up with poles, too, steel, wood, aluminum, and downed saplings that I've collected over the years.
Because of an accident I simpy cannot handle heavy gear any more so I am giving nearly everything I have to my son, who is coming over today to get it. I need to go ultra-light, hence my move to hammock camping.
I'll have to stick with my 10 x12 blue poly tarp for now but look forward to silnylon and eventually a cuben.
We had so much fun as a kids with my family using an old-fashioned 10 x 10, four-paneled canvas tarp with tie-outs around the edges and in the middle. So, I like the Cooke Custom Sewing Tundra tarps. But some day I intend to make a cuben. A three panel cuben would make a tarp nominally 13' long and then each panel could be 10' and there you have it.
