When the our wagon was put into storage in the barn, the driver's window was plexiglass. The plastic was enough to keep the rain out, but if a determined critter wanted to get in, they could. The back side of the barn was the cover for a condo of ground hogs. Dad thought it would be wise to put out some poison to help curb the population of rodents. Long story short, a massive ground hog made its way through the window, and died on the passenger side floor mat. I still have the floor mat, and yes, it scrubbed up just fine.
