Suprised no one has ever gotten into the business of setting up theft deterrent systems for things like skis. Simple RFID chip inside the ski, receivers installed at lifts which would just turn on a small red flashy with a buzzer when skis/boards/boots with a chip that have been reported 'stolen'. Hell, equipment fees would be cheap as all heck for this, offer to install the prevention system for free in large ski areas.
Anyone got 200 grand to put down on it?
