You all know I'm always up for a good road trip. In fact, I grew up taking long road trips pretty much every summer of my life for family vacations and other adventures. Here is an article about some especially scenic road trips in the U.S..
Which of these have I been on? Hmmm. I think I've been on parts of Route 1, years and years ago, but it might have been at night. Rob and I have been on the Blue Ridge Parkway which is very pretty. I've been to the Rockies in Colorado many times. So pretty, one of my favorite places ever.
Anyway, if you're looking for a good road trip, check these recommendations out. They're all over the U.S. so you should be able to find one that's not impossibly far away from you.
