This weekend, I was to fly from Baltimore to Columbus to visit family. Only, I got bumped from my seat by the airline (whose name I won't say, only that it is the directional oppositie of Northeast.) At any rate, I ended up driving from DC to Columbus, and made it in a shade under 6 hours. If I had taken back roads--such as Rt. 40--I'd still be driving back.
God bless the Interstate system. Also, I-68 through western Maryland and West Virginia is actually a very pretty route, I don't mind driving it at all.
