I did the East to West coast road trip ( NYC to LA ) via Washington, Knoxville, Nashville, Memphis, Littlerock, Dallas, Amarillo, Albuquerque, Vegas, San Diego and finally hit LA. Those were the main places we hit along the route but with many other smaller towns etc along the way. Total of 4562 Miles and hitting 14 states over 3 weeks and would do it again in a heart beat, it was a road trip and a half
Next one will probably be a West coast road trip from Seattle to San Diego.
