Just thought I would point out a comment that was received on a very old post about our Ohio county trip.
I randomly came across your blog while googling something completely unrelated about PC. I'm from West Alexandria and I find it totally hilarious that you ended your trip through every county of Ohio in the extremely small town I grew up in! Great blog and great idea for a mini-road trip! My friends and I might just have to attempt to do it ourselves. Oh and for the record, there are "Welcome to Preble County signs" elsewhere, just not on 35 for some strange reason! ODOT works in mysterious ways!
