Most people doing the great American roadtrip think Rushmore is a must, and most people have barely heard of the badlands. I'm gonna let you in on a secret, Rushmore is not as amazing as you think it is. They're tiny and it's boring. A short drive away (in the across America timeframe) is the Badlands. And they're not overrated, they're underrated and amazing. Spend your time in this amazing American landscape (and pass up Rushmore).
