Chad is having trouble with rodents chewing on the wiring in his car. It’s a problem in labs, too, where something will occasionally chew through some data cable (which was not as serious as when they chewed into the bag of M&M’s left on the lab bench, but try convincing the boss of that). I noticed one comment that was similar to my thought: float the data lines at a kiloVolt. That’ll larn them varmints.
