After the top of the dead pine tree crushed my last run cover I was trying to find something with a better design than my PVC/chicken wire and tarp set up. I found this 'Car Port' at Agri Supply for less than I could rig something. It is a very tight fit over my dog run, because the run is supposed to be 10 x 20 and is 9.5 x 22. so two feet at the end has a wire cover. I am very very happy with this.
