Has anyone ever used an old car as a place to taint their meats? Considering they almost become an oven sometimes I was thinking an old car in full sun all day would be just that, and would speed up the tainting process greatly.

Good idea. If you have an old truck or car sitting out back it makes a good place to put various items for drying ginseng or aging glands and meats. Helps protect them from larger animals also. You still have to deal with mice..It gets quite warm behind a wind shield in those vehicles.

I knew an old fur buyer that dried lots of ginseng, blood root, golden seal and yucca roots in a couple old trucks he had sitting out back. I would be concerned of potential theft once anyone else became aware of his drying method. I just happened to notice his set up on a visit but didn't comment to him.

My boss in high school had an old truck on his property with full operating windows and doors. Motor was shot. He put buckets of bait and lure in there and shut the door. Kept the windows up to keep flies and mice out.
Always warned me not to open the door on a hot day.
