I am planning a 3 week road trip in June. The route I have planned covers 6600 miles. I plan to go from Atlanta to the Gateway arch, Mount Rushmore, Yellowstone, Redwood National, Golden Gate Bridge, Hollywood, Hoover dam, Grand Canyon, Four Corners, Carlsbad caverns, Civil rights museum in Memphis, back to Atlanta. There are 3 adults who will share the driving. I know that I will not be able to enjoy each site the way that I would like. My question for the forum is am I being too ambitious for 3 weeks? I made a schedule that looks doable with maximum 600 miles in a driving day. Wondering if I should pare down my list of sites I would like to visit. Thanks in advance for your responses!
