Took a 400km daytrip today, to do some exploring in the "forgotten" corner of Virginia. Stumbled across excellent roads, scenic views, and no one else. I'd go tens of kms without meeting another car on the road. Also went to a state park......and saw all of 3 other people there.
The isolation wasn't so surprising, but still remarkable at how long it takes to travel a relatively short distance given the difficult terrain. Roads really can only run along the valleys; the few crossings across the ridges were obviously difficult to engineer and not so easy to drive. Nonetheless, the roads running in the valleys had a nice flow and corners......just the sort of grand touring the 3er is the best at.
