Using another idea from Pintrest, I wanted to do a welded wire arch over the concrete pad. Being unable to get cattle panels here in our part of the country (not too much cattle here), I opted for the heaviest gauge fencing I could find. It would not stand by itself, so we used angle iron for posts about 6.5' tall on the sides and supported the "roof" with a post. The 2 lengths of fencing are tie-wrapped together.
