Travelling to the USA in October this year for an east coast road trip with an American mate. Starting in Maryland, doing a circuit inland and back around along the coast. We plan to camp where ever possible, cook our own meals and use gym memberships to use their showers. Really pumped for the trip and I think we got most of the important stuff covered. Do any anons have tips about camping in the us? Is it pretty straight forward just to peg up some tents behind a car in national parks or are there hoops to jump through or precautions to take?
