I'm guessing they are. They've really taken off as far as feeding animals go. One of the guys we buy feed through put up a 500 head unit last fall and right away he ordered a 1,000 head unit.

The guy we feed for is putting up a 2000 head hoop building. Going to be 70-ish x 1200'. Guessing multiple tarps. Should be an interesting project. I'll probably get some pictures.
