When I was a kid my dad bought me a beat up '65 Barracuda that had been stolen then recovered from a sherrif's dept. I found a spoon that had been used to cook drugs.
In the Challenger we found tons of stuff. Hardhats, jumper cables, lots of parts, some go to the car some don't. Ther was white powerd all over the back carpet. We were afraid it was rat killer dust but it turned out to soap.
