well, i'm going low tech but i think it will be ok..picked up a industrial duty painting plastic sheet..10 ft x 25 ft..more than long enough to fold back under and put bungies on..i don't see why it wouldn't work..not as high tech as a bag..but 10 dollars versus 60 and shipping..i've spent a lot of money on stuff this year and i'm tired of it (this year, anyhow)
