Not so much paradoxes, but a couple of really incongruous observations at local businesses.
There is a paving company about 25 minutes from here that a couple runs out of their house. The house is a dumpy-looking place 'way back from the road on a rutted, muddy (unpaved, of course) driveway. When I first saw the sign there, I thought it was a little free advertising for the company that had been hired to do the paving. Nope!
There is another small business much closer that is run out of a house. Again, the house is a shabby-looking dump, poorly maintained, with a gravel drive, and a yard that consists of dirt and immobile vehicles - just a perfect eyesore. What does that guy do? His sign says that he does home renovations and remodeling. He may do great work, but judging from the condition of his own place, I doubt it.
