I do. Riding coast to coast is a worthy goal. Regardless of the route you will meet interesting people, see interesting things, and eat interesting food. I found the scenery on the Southern Tier mostly pretty boring, but greatly enjoyed the people and the food. The TA was pretty boring scenery wise in eastern Colorado and Kansas, but the people were exceptionally kind and hospitable. Also cranking across some long boring miles can be satisfying in a way that makes the highlights stand out all the more.

National parks and the like make great focal points during a long tour, but experiencing small town and rural settings and people is really seeing what the country is about IMO.
