Jerry,
Know the stretch well - mid 20th century design / 21st century speeds. But you have to admit, they layed down some sweet asphalt the last time. Its tight, but its smooooooth. As Grump mentioned, take a spin on 79 toward the airport and then the parkway - Now there's where they'll give ya a scare. I spent what seemed an eternity on that stretch one day. Took the back way to Beaver Co., the into WVA. Coming back I thought I'd take a short cut - NO MORE. One trip on that stretch and Rt. 70 is quite roomy.
