I just surpassed 500 miles (507) and just passed South Vienna, OH. South Vienna, per their web site, is still a center of the farming community and has about 500 residents. It was originally called Vienna (after Vienna, Austria) but it had to change its name because a similarly named town existed. It changed to Vienna Crossroads and then finally to South Vienna in 1908.
Check out the great picture from the web site below.
