I sure it has been mentioned in this thread somewhere. The problem is the average visitor to the area will leave the Walmart canopy up for the duration of their stay (or until a storm knocks it over) and they do not take it back down (or pick up the twisted pieces) when they depart. We see this on the beach at High Pointe every time we are there. The other problem is the storms sometimes blow the canopy up on the dunes and they are not reachable. So once again a few are screwing things for many. We leave nothing behind. If I see my kid drop something wheather they mean to or not I make them pick it up or chase it down in the wind.
