Here's what I was thinking.  In a nut shell, could we use window screen, probably the black vinyl stuff (some stuff I've seen is pretty dark and hard to see through), and about every ten feet have velcro (did I spell that right) glued or sewn on.  Then just have the other half of the velcro on the poles.  We could just roll it up when done, and the wind should just go right through it.  

Or maybe even just cut panels instead of having a roll.  

Does this sound workable or something to build on?
