Speaking of carrying money...

I had a neighbor who was an Ag pilot (crop duster). In the late 70s, he crashed his plane. He bought another, but he rebuilt the crashed Piper Pawnee. He found a buyer in Mexico, and flew the plane to an airport on the border. He received a briefcase with $18,000 in cash (about $64k in today's dollars) and flew home on Southwest, carrying the briefcase.

Last Christmas day, my 2 brother in laws and i loaded up in the truck and drove 6 or so hours and across state lines with $30k in hundred dollar bills to buy a trailer. We had to get the deal done before the first of the year and Christmas day was the only day that everyone's schedule worked out. we get to the town in central Nebraska and it is getting dark. the trailer checks out but we want to hook it up to the truck to make sure it airs up and the brakes release. It won't air up. So a troubleshooting we go. We are all carrying, and im doing a good job of keeping mine concealed as i go under and around the trailer following air lines. It turns out the leveling valve is stuck and we decide to bypass it to get the trailer home. Meanwhile, while we are working, my brother in law has forgot about his pistol and the handle of his pistol is hanging out of his coat pocket. The widow and her son we are buying the trailer from get somewhat alarmed. We reassure them that we are honest folk, and are only carrying because we are traveling with $30,000 in cash. we pray to God that we don't have to use our weapons to defend ourselves, and if they want to call local law enforcement to keep an eye on things, it is fine with us. Anyway, we get the air on the trailer straightened out, go in their house (its 9pm and completely dark now) count the cash, sign the title and bill of sale, shake hands, and head home.
