I remember a TV series called The Immigrants, about one Norwegian family's move to Minnesota. Their farm back in Norway had a few inches of topsoil over glacial cobble and bedrock. When they got to Minnesota, the father stuck a rod down into the topsoil and it went down five feet with no rocks. Then he tried a few more places: Same result. He knew they had arrived in Heaven.

The reason I thought of this today, is that I am digging post holes to put chain link around my solar array. Some holes I dig with a water jet in about one minute. Some involve a lot of rocks and cursing. Pandemic result: Chain ink fabric has gone up 250%, and Lowes and Home Depot have zero stock. Fortunately, my good neighbor has some used rolls from a fence he replaced I can get for the hauling!

We're flying electric helicopters on Mars yet you can't turn on your clothes dryer in Texas. That's because scientists are in charge of Mars, and Republicans are in charge of Texas.
