WHERE IS THE BEST ROAD BIKING IN THE U.S.?

I live in the Midwest and want to get to another part of America for some epic road biking. I’ve ridden in the Colorado Rockies a bit. Where else would you recommend?
A:
You’re in a pretty amazing region for road biking already, Tina. But I understand that riding on flat pavement all the time can get a little old. If you’re looking to venture outside of the Midwest, I’d point you to these three places.

Hill Country, Texas
Rogue Valley, Oregon
Champlain Valley, Vermont
