“In total, this road trip spans 14,498 miles (23,333 km) of road and will take roughly 2 months to fully enjoy, depending on your pace. I’ve designed this road trip to form a circle around the U.S., so you can hop on at any point and proceed whatever direction you like. Just make sure to follow the agenda from that point on if you want to follow the optimal route!”
