To switch gears a bit, let me show you what was to my California eyes a surprising sight.
The picture you're looking at is of an oil pump jack. I saw a few of these in California, but always in rural or deserted areas or at least never close to a building. In Oklahoma, these are all over the place, and frequently in among shopping centers and houses. You can't really tell from the picture, but that jack is in the parking lot of a mall. I'm not sure, but I think the buildings were erected after the pump jacks, which were probably there when there was nothing else around. It would explain the odd placement of them. Anyway, just thought I'd share the common Oklahoma "oddity."
