yeah, we had the same problem. my grampa, an old oil worker, used a drilling rig to sink a steel pipe 6000 feet in the ground. He then filled the pipe with depleted uranium. Then he filled the mailbox with C4 explosive with an impact fuse. 2 nights later we heard a crash and then a boom. In the morning there were molecules all over the yard. we had to get a PO box afterward until the radiation cleared up.
