Of all the manias, without a doubt the most widespread is morning lovemaking. Men always want to at this hour, and end up persuading women. Not a problem if one lives sheltered within the four walls of a house. So let’s imagine a homeless couple who set up on some parcel of open ground or out in the desert; for them the act requires taking cover under the shade of a tree or a bush or a wall. In time the mechanical thrusts and shoves will inevitably begin to mark on the ground, and in the end there will always be some person devising theories that link these marks with spacecraft landings. This is what happened with Kent Fall, the mayor of Ely, who on a morning in 1982 saw very deep marks in the shade of the poplar that found water, deep and gestural and arithmetic, bored into the earth. Above, hanging from one of the branches, he found two pairs of shoes.
