I was driving along Speedway a couple of days ago in the area of the University of Arizona. In front of me at a traffic signal was a Jeep Wrangler. The vanity plate was DRYBONZ. There was a bumper sticker in the rear window that said "Bring Back The Pleistocene".
With those clues it wasn't very hard to determine he/she was a paleontologist.
No doubt this summer the Jeep will be far off the beaten path as the paleontologist scours the earth searching for a fossil from the Pleistocene.
