Heck the turnpike is fine, on weekdays. Weekends can be a busy near the tollbooths. It was fun back in the day, drag race from the toolbooth, pay your quarter, get that green light drop the clutch on my 86 Mustang GT. Let it roll, (Beep)
But I digress. Its like $2 a axle now or something outrageous.
Weekends have a lot of ' oHIo ' & PA travelers going back and forth to the beaches. Its Like shift change.
During the week I haven't had an issue. Have some torque to pull them 6% grades, Flat top north is 7% I think. They have truck lanes on the uphill grades, if you have spark plugs, so its good
Camp Creek is a nice campground, State of West Virginia establishment, and close to 77/Turnpike, right at the bottom of Flat Top.
They are always working on the Turnpike somewhere. They have their own website for toll information.
I like to pay for the car behind me sometimes, if they have a bunch of kids and I pass them, or see them in the mirror. Its fun. I always wonder if it give the parents a smile, makes a difference in their day , makes it easier. I often wonder,
safe travels ! Have a good one !
