I-68 is a nice, relaxed drive. From Columbus, I-70 through Wheeling to New Stanton, then I-79 down to Morgantown WV, then east over to Cheat Lake to pick up I-68, follow that to I-70 in Hancock MD, then I-70 east to Balto & south to DC through various methods. Once you're east of Hagertown, you have options.
We came east on the PA Turnpike last August, from the Pittsburgh area. Nothing spectacular, but more expensive than the Interstates, obviously. Parts of the PAP TPK are repaved but they were also working on long stretches of it. By now, one would hope the new stuff is done, but it was a rough winter. Not sure of it now.
Always remember, you're a unique individual - just like the other 7 billion people on the planet...
