This is a stick with a heavy steel weight on it. Be very careful, it hurts if you hit her in the head! But it makes a nice bang when you hit it on a properly inflated tire! You don't know what else you could use it for and don't get caught in some big cities or states if it's within range while driving. Or hidden. I keep mine behind the passenger seat. That way I can start my ride by tapping the passenger wheel, going up to the driver's front wheel, going down and around the van, and going back down on the passenger side. End up right where I keep it. Far enough away that no one could throw a dangerous weapon at me!
