I'm having my reception in a riding arena and the flooring is sand. I don't want sand and would like to get flooring. The room is 60ft by 80 ft. I thought about plywood but even that will be very expensive to cover. Does any one have any cheap suggestions? I can't change the venue because it was crush my fiance and his family. He wants to have it at his family farm. I'm trying to work with what I have.
