First time cross country traveler looking for some insights from the more experienced professional outlook. We are starting in PA, two hours out of philly. We are traveling to Nashville, TN to see a friend in the army who is stationed. We figured this would take one day approx. 13 hours to arrive at our destination the first day. From there we plan on traveling to Oklahoma city, where my other friend is based because of the Air Force. Oklahoma we are suppose to drive to Arizona for Hellcity, a tattoo convention and from there finally making it to Huntington beach, Cali. Few questions. Which would be the easiest to drive, where is the good food and historical places located? Is this a good idea? Money is not a factor in this excursion. Thoughts, comments and constructive criticism is expected. Thanks for reading and hope you all have some information for me.
