What is the best way to protect the King Pin from kids knocking them selves out and or cutting there heads. I don't want to spend o bunch of money on a stabilizer so what other options, I've used nood...
The neighbor down the street wraps the pinbox with foam and holds it in place with duct tape.
I would put something on the ground to keep kids and others from walking into the area. Orange cones, A paper tube used for forming concrete pylons, a big flower pot...etc. Most folks are looking down....
