Rodents just seem to like rubber as well as salt. Our family has land and a cabin in the San Juan's, I try to go once a year. Those mormots have given many vehicles heck with wiring; four wheelers also. Here in Texas, I have big issues in a shop of mine with pack rats eating the 12/2 wiring. Of course, they don't touch the ones with constant power; but those that the power is only one when tool is in use get eaten. I have to check wires often.

Porcupines were mentioned. Not really an expert, but they LOVE new plywood. Those dudes'll eat their weight in a piece of plywood in a night.

Phat, I love the chicken wire set-up. When I go to Colorado, where to leave my truck is my biggest worry.
