[Land-speed] Pit Shade

[Elon]

We have all seen the shades that are perforated and let the area breathe. I
talked to someone last year who had a very large cover. He said he buys hay
covers. The problem is that all the PERFORATED covers I have seen are black
or a dark color. They do a great job of filtering the sunlight but due to
their dark color they absorb a lot of heat.  I was thinking a perforated,
light or silver colored tarp would be the best of both worlds. Has anybody
seen such material?   -Elon
