What's the worst "nest" you've found in an A-body?

We have pretty constant issues with mice around here, my Duster has been sitting 2 years in our garage and there's definitely evidence of mice getting in the interior... had an old bag of beef jerky that looked like it got hit with a lawnmower lol. We had a family living in the garage, killed the 2 parents and was still seeing mice so I had to get better traps, killed 3 more smaller mice now we're finally good. Until spring comes of course. Thank God we have cats they kill so many vermin during the warmer months.
