Mouse condos

I've been working on my new toy, the '71 Dodge D-100. I got to trying to get rid of the barn smell. Leaving it open for three days and pulling the carpet and seats didn't get rid of it. While the truck did come out of a barn, I didn't want it to smell like that all the time. The cowl is pretty rusted and I was going to weld it up but decided to just fill it with expanding foam and some bondo. If it was going to be a show truck, I'd do it right. It's gonna be a rat rod so who cares? The passenger side had some cotton fluff showing so I figured there was a mouse nest in there. Boy howdy was there! Using a 2 1/2 gallon shop vac, I started cleaning it out. After a bit, I needed a screwdrver to drag the fluff back. I filled the vacuum twice with mouse nest. A couple of days later, I looked in there and I wasn't anywhere near done. Using a bent coat hangar, I filled that vacuum twice more before it was clear. This is not a mouse nest. It's a condominium. The neighborhood cats are having a buffet too. They even nailed the door mouse and left it's uniform laying next to the truck. (I know, that was a weak and lame joke.)
