As the slogan goes, “skateboarding is not a crime.” But for property-owners increasingly pissed at finding their rails and benches crapped up by teenagers using them for serious grinding on the weekends, skateboarding is at least a hassle. So now there’s a company called Skatestoppers, and they sell these little metal brackets that prevent skateboarders from enjoying a nice smooth surface. (The company slogan: “Because signs are not enough!”) That’s one of the brackets pictured above, and the web site describes them thusly:

SKATESTOPPERS® skate deterrents are specially designed brackets that deter unwanted skating/biking by eliminating the long, smooth edges that skaters and bikers seek out. In effect, they are speed bumps for your walls, handrails, curbs, etc.

Skatestoppers also sells these little metal discs that can be affixed to flat concrete, making a smooth surface bumpy. They’ve got an example picture here, and it’s oddly beautiful! But then again, so is skateboarding.
