Our beautifully awesome ATV got stolen today. My dad was a dumbass and left the thing on the trailer in the driveway even after he went and retrieved the key to the disc brake lock (long story), and so the trailer has been in the driveway for a month or so having people walk past it, able to plan to take the damn thing. There's a pretty much impossible to cut ball lock on the part where you hitch it to the back of a car, but that can be remedied with duct tape and tie-down cords.
Apparently, there've been people stealing trailers in this general area of town for a while, but if they were going for a trailer, we have a new one without a broken tail light right beside our house.
When my dad found out, he drove around the neighborhood with a handgun with the magazine filled with some pretty hurtful stuff. It was scary, but he put his gun away after a while and went back to work.
