You know Bill I had a similar discussion over the weekend with a friend regarding one of the Chrysler plants. While staking the ground for an event near the plant. It took several attempts to drive them into the ground for some reason. Later, an employee who had been around since back in the day (60's or 70's) took a look at what was going on. Then mentioned that there might be a problem cause that was the location where the junked engine block were buried. We laughed about it thinking how many Hemis might be in there and who might like to go digging there someday...
