I don't have any pictures, but I saw a Google car with a camera mounted on the top near Easton Town Center here in Columbus, Ohio.

Sweet, I am from Columbus too! :)
(though I don't frequent Easton Mall)

I saw one on I70 heading east out of Columbus last week. It was getting on 270 North, traveling at least 65-70, it was around 5pm so I imagine they were heading to a hotel in the area?

I saw one today around 1pm on Tuttle Crossing blvd.
