Last summer I got a phone call from our club's range manager. He asked me to bring my bow tools over to his house for an emergency housecall (also mentioned he had a fresh case of beer, but that's beside the point

).
He and his cousin, who was visiting from out of town, had been out at the range shooting. His cousin had a brand new Mathews. He'd shot at one of our 3D's and commenced to have his own 'bad day.' He had a cell phone clipped to his belt. At the shot, his string snatched that phone off his belt. It got caught between the string and cam and the string cut the phone clean in two! I mean two completely seperate pieces, discounting the shrapnel that got scattered around the accident site. You can still see little pieces of circuit board laying around that shooting station.
Of course, the string popped out of the track, and the cable also bounced out if it's track.
So, got to his house and, after I got my laughter under control and reestablished a normal breathing pattern, I pressed the bow down, inspected everything, smoothed off a couple of burrs that had been dinged into the cam and put his bow back together.
See? Some folks can have days a LOT worse than yours and not do any permanent damage to their bow. [8D]
