Cross-country trip advice
My brother, cousin, and I (each in our early 20's) are planning a road trip from NY to CA and have roughly planned the following route: New York, Nashville, New Orleans, San Antonio, Grand Canyon, San Diego, LA, San Francisco, Yellowstone NP, Mount Rushmore, Chicago, and back home to NY. I have travelled up and down the east coast but have never even been out of the eastern time zone. I am eager to see as much as possible so I hope we are not being too ambitious here.
Having no experience with a trip of this magnitude, we estimated the trip would take about 3 weeks. Does this sound like a reasonable goal to the more experienced road trippers out there? We have been considering cutting out 1 or 2 of the California cities.
I would appreciate any general advice that you are willing to give. Also, suggestions of things to do or places to visit along the way would be a great help. Thanks!
