I had one not quite that big that I got at a yard sale (probably was 15 x 15) for about $150 years ago. Old smelly canvas thing. Set it up to air out so we could go camping with my wife's family. Along came a huge wind storm and picked it up and blew it through the clothes line pole (3" steel pipe). The tent got the worst of it. The insurance company paid $1300 for it. Now we stay at hotels!
