I finally found the source of that smell in the truck. (Not me for a change...)

Mrs. Meece built a humungous nest on top of the cabin air filter behind the glove box. Complete with dead babies...

My dad has a CJ Jeep in his shop that hasn't run in at least a decade, that he's working on getting running for a rancher.

Pulled the engine & there was a next in the bell housing of the transmission, complete with expired mice.

Garaged Motorcycle mufflers and air boxes are Mickey Mouse's favorite food storage spaces.

The dealership I work at had a Electra Glide brought in for radio work. As unbelievable as it sounds one made a nest in the fairing. Mouse urine was the culprit together with chewed wiring.
