Man, I bought one of those pop-open ground blinds, and took it home. Since it's raining outside, I threw it open into the den. As it popped open, it broke my overhead light, and now I can't figure out how to close it. It came with one sheet of paper written by somebody w/very little grasp of the english language. Apparently, I'm supposed to grab and twist it somehow, and it will magically go back into a trash-can lid sized disc. Yeah, right. Anyone know how to close these things?
