On parking: in the USA you will be astounded at the parking space available-other than in big cities where it tends toward paid parking. As to lodging there are B&B online lists-Tripadvisor is a great tool for lodging.The motels here can be just as boring as those in Europe,esp. at the lower part of the food chain. You could also buy camping gear cheaply here for that trip & for very little more than one nights stay in a better hotel. Enjoy & ask que tions...Too bad your missing the other end of us but wise to focus on an area & do it well.
"If I had my life to live over,I'd dare to make more mistakes next time...I'd relax,I'd limber up.I'd be sillier than this trip, take fewer things seriously, I would take more chances... take more trips...climb more mountains...swim more rivers...eat more ice cream." Jorge Luis Borges, at age 85
