openmike, you beat me to it! I was just going to wax eloquent about William Least Heat Moon's great book, Blue Highways. He also factored in some other factors, ie whether there was a Hav-a-hank sales promotional display, sold combs, and BC or Stanbac headache powders. These things could actually add to the Calendar count in the Greasy spoon, but make no mistake, I still seek these places out when travelling and often tell my wife as I am turning in the parking lot, "this looks like a 5 calendar Resturant."
