I've been at a racetrack where an ez-up with over 200 pounds of weights attached turned into a 4 legged flying medevial mace. It wasn't pretty.
Best ever "don't touch" was the kid sitting in the front seat of a car eating a dairy queen messy as hell ice cream cone. They, mom, had no idea who the car belonged to. Nicely done. Another reason not to stray to far. You never know if you are the winner of the "dumbass in attendance" door prize!
Have fun at the show, don't sweat the oem, not correct wannan-be judges walking around.
