Dick-- I remember that photo also but I can't locate it from the Search engine! It was made, I think, from a plastic tarp and some plastic conduit. I don't remember how they secured it but I remember seeing the picture. Let us know if you come up with it! We're hot up here in Omaha too! It's 87 at this moment and the humidity is hitting about 63%. We need to head Northwest for some cool air!!
