Mike noted,
most of them make a good living off of people.
That reminds me of an incident when I was a young reporter, either 1969 or '70, living on the Eastern Shore of Maryland. I was so poor that I could only buy old used tires for my car. They cost $2 each. Of course these were worn slick and continually blowing out or just going flat. (There's a strange story about where they blew out -- always across a field from a farmhouse of some unrelated people whose name happened to be Bauman. I would hike to their home and borrow the same spanner wrench, or whatever it is, to work on my tire bolts.) Anyway, one time something happened -- maybe a tire went flat and I didn't have a spare or maybe I just ran out of gas. At any rate, I had to hitchhike to the little weekly paper in Selbyville, Del. One of these revivalist-type preachers gave me a ride. I thought we were getting along all right, but when we got to town, he tried to hit me up for gas money! Being broke, I didn't give him any. But still. -- Joe
