Two of my friends and I are currently trying to plan a road trip for next summer. We have a few places in mind but have no clue on where to begin planning or searching or preparing. We know we would like visit the Badlands, Yellowstone National Park, and coastal California (spending most of our time in California). We are from Philadelphia, Pennsylvania. So any tips and tricks and memorable places to see. Our backgrounds are def. a great mix...one of us is a nurse, one is a school teacher, and one is a firefighter, so we are up for any types of adventures and sights to see.
