There wasn't a line at the check-in desk (although I had a hard time getting my wallet with my ID back from the granny at the desk). Most of the electronic booths were full, but I didn't have to wait. That was a little busier than normal, but it might be because this was the first general election with the electronic booths so people were voting more slowly. The machine printed a copy of my votes for confirmation and held that in the machine for recounts which smart way to do it.
My only problem was that I completely forgot my promise to literally hold my nose shut while voting for DeWine. :-(
