That is .25 ounces per square yard if I did that right. I'd love to get a few yards of that material.

If you've got a long extension ladder and a pocket knife, I know where you can get some... :aetsch:

According to that article (and the way I interpret it) that weight is for the whole roof. I'm wondering if it's not per panel...?

That was the way I read it too. 68 pounds is 1088 ounces and the tarp is >395,000 square feet, so that would be at least 43888.8 Sq yards. 1088/43888.8 would be 0.0247. So I was off by a factor of 10. That means it would be 0.025 ounces per square yard. An 8x10 tarp would be 0.22 ounces.

Well, that being said,

What... is the air-speed velocity of an unladen swallow?

I still would like to get a few yards of that stuff. Enough to make a pack, tarp, and hammock!

(and yes the shadows on the dome near by are people working on the hole and yes it was a pain in the ass, because the hole was right above us too so we had to move our setup)

I'm not surprised it gets holes.

Atlanta air pollution has more PPM than that material.

That's why you should go with a retractable roof. Cheapskates.
