We (husband, 12 year old son & I) will be driving from Cincinnati area to Pittsburgh on a Saturday in April, on our way to the ballgame that night. Looking for suggestions on the route to take. We will have the majority of the day, so total highway is not necessary. Anything we should be sure to see, or a great place for lunch? We may possibly drive part of the way Friday night, so to have more time on Saturday. Thanks in advance!
