Where is the last best place for road cycling?

Some definitions are needed:
1. "best place": Define it yourself. For me, in order of import, it would be a road with:
a. Light traffic.
b. Bike friendly traffic.
c. Decent pavement. Short and firm sections of gravel/dirt would be OK.
d. Road features; i.e., some curves and hills, not just a straight, flat line through the desert.
e. Scenery.
f. Reasonable weather.
2. "last": Since I suspect nobody will give away the secret of a place that actually exists today, for fear we will all move there and ruin it, I am naming my place from the past.

I lived in Lancaster County PA in the 1980's, in the heart of Amish country and could ride out of my garage, turn right in about 50 yards, and within a quarter mile be on a small country road lined with Amish farms. Traffic was very light, and I could often go for 15 miles and only be passed by a small handful of cars. Covered wood bridges and horse and buggy traffic were common. For more mileage than 15, I had to endure a short stretch of road for less than a mile that had normal traffic but back then, and back there, normal traffic was something I would love to find today.

If you do know a great place that exists today, I think you can be safe in revealing it. I am sure we will all promise to keep it secret.
