I have been restoring old cars for many years and have brought home well over a hundred cars for parts cars or fixer uppers. I always Loved walking through a salvage yard as feeling every car had a story. When bringing a car home I couldn't wait to see what might have been left in the trunk and than take out the seats. I have found many old coins,Watches, pocket knives,a gun,old baseball cards and numerous items in the trunk, involving everything from just junk to antiques that were worth alot more than what I might have gave for the vehicle.
There were also things in the vehicles that I didn't want to find, like hornets nest, wasp, yellow jackets, Snakes. The one of the craziest was a snake about 6ft long coming out of a 1957 Chevy tailight that had been bedded in the gas tank.
One of my worst experiences that evolved around treasure to a car guy and a bad experience was I had found a 1937 Ford Coupe that was mostly complete and all original. It was worth alot of money in it's condition but it had sat for many yrs and had a Huge Hornets nest inside that wasn't letting nothing to close without a defensive attack. I decided to just wait a few months and let winter be my offense. The Freezing cold finally came and I went to retrieve the car to find that a huge tree had fell right through the middle of it, destroying most everything. It was a sad day,lol.
