<human>: I'm going on a road trip with my friends. What are some good places to see on the way?
<bot>: 
1. The Grand Canyon is a must-see destination for any road trip.
2. You can also visit Yellowstone National Park, which has plenty of wildlife and stunning scenery.
3. Other great stops include Mount Rushmore in South Dakota, Custer State Park in South Dakota, and Badlands National Park in South Dakota.
