We took #906 (1967 GT500) out Saturday the 10th with a few friends with various make cars on a drive from Mount Vernon, WA. to Winthrop, WA., across the North Cross Highway for a beautiful drive. About 275 miles roundtrip. One of the most beautiful drives you'll encounter. Mountain passes about 5700 feet in elevation, light traffic, 3 large dams on the Skagit River that produce power for the City of Seattle and plenty of pull-outs to take in the views. Oh, cold beer at each end of the drive also!
