In 1993 the back porch of my apartment looked out on the 13th tee of the golf course i was working at. People would park at these apartment's and sneak on to the course by starting on the 13th hole. We had just installed a toro OSMAC control system for the single row irrigation system. There were toro 670 on tee's, 690's in the fairway and 650's around the green's. You could control individual head's with a handheld radio. I got aggravated seeing people sneak on so i started sitting on my back porch with the handheld and right when they were about to hit their tee ball i would turn on the water at the tee, that was fairly discouraging for the golfer, but was usually not enough to make them quit, so i would follow them down the fairway with the rotor's, right when a person was going to hit, i would try to get them wet. If they made it to the green, i would turn on the green as they putted. This was 5 650's at once, and that was usually a good enough soaking to make them quit and leave. I only did this six or seven time's but i thought it was hilarious.
