ACME,
I live in Parkersburg. Hope to see you while you're here!
I guess my best suggestion is that when you come down, don't, for crying out loud, use I90 to I77 - unless you're leaving late and need to make time. Both roads are flat, straight, and boring as heck. I've been that way a few times on those roads by car. For an extra 20 minutes or so you can take I79 to US 50. I've never been on 79 north of Pittsburgh, but south of there it's OK, and Route 50 is a treat. But go around the city rather than through it. If I was doing it, I'd consider 219 to 119 to Morgantown then 79 to 50. That would add about 2 hours though.
Regarding Deal's Gap, there's a group from OhioRiders.net that's going down the first weekend in June. I'd probably be going but my anniversary is that weekend. I'd like to have another one.

But there are a lot of great roads near Parkersburg. I like WV 21 south to Ripley or a bit farther then there are some great roads from there. Or if you like SOLID twisties try OH 555 from the south end, starting just a few miles from PKB. Another famous twisties road is OH 26 from Marietta OH to Woodsfield.
If you haven't tried it yet, check Motorcycleroads.com and check the routes near PKB. You could spend days nearby.
Someday, I'm going to cross the mountains to Roanoke VA, then down the Blue Ridge Parkway to NC and the gap, then back through TN, KY to home.
Send me a PM when you get closer to the day of the trip.
Chris
