When I die, I think my wife may have other plans for the trailer than pushing it, and me, into the Grand Canyon (what about those people on the rafts in the river?).
But if she got a $1,000 old Airstream just needing "a little work", that would be cheaper than a casket. Just dig a big hole on our land and bury it and me and save some money to spend on a big departure party.
Imagine what the anthropologists will guess when they dig it (and me) up in 10,000 years—he must have been a king to be buried in a big metal casket—he had a kitchen to prepare foods for his journeys too. Maybe I'll tell her to put some strange tools (an egg beater comes to mind) surrounding me so the anthropologists have something more to speculate about. They might think an egg beater was a symbol of my regal authority.
