[Vanhackspace] Toorcamp needs coordination

[Alexandre Harvey]

The first structure there, is more what i had in mind. So i take it 3/4"
would work, its flexible yet ridged, the idea is to cut each 10' section in
half or so to make the 20' ribs after you connect 4 pieces back together
using a pvc connector with a bolt through it. Larger maybe possible, but i
thought that 15x20 tarp would make a smaller and a little more portable
large shelter.

Dan if you are around and heading to toorcamp, I could use your assistance
getting this put together in time.
