Actually, most of my weird loads were in my pre-expediting courier days in the late '80's - early '90's where we would take anything that would fit in the truck.(In this case, my trusty Astro cargo van).
*Got a load of a thousand pounds of frozen egg whites is cans out of central Ohio. The pallet wouldn't fit, so the cans were loaded loose. Took those to Minneapolis where it took some time to find someone to help me unload the formerly frozen cans. On the way back home, got a chance to stop at Wisconsin Dells and take a helicopter ride, so it wasn't that bad a run.
*Astro van again. A short run of 50 miles with a 2,000 pound granite table for a machine shop. Didn't run over 50 mph on the interstate because the little truck was wandering so badly. We got paid for extra weight with that company but not enough to justify a broken suspension. (Luckily, it was alright)
*A load from Cincinnati to Evansville, IN. A truck full of rubber ducks for a Rubber Duck Regatta, loaded with a coal shovel.
*A prototype computer chip that fit into my shirt pocket. I was warned by the shipper that it was worth hundreds of thousand of dollars (he felt compelled to tell me that it was worth more than me), so I felt badly when it later slipped out of my pocket and fell in a mud puddle. I washed it off and it was fine.
