Hi! We are planning a road trip for the month of June, driving a Subaru Forester camping and moteling. We'll leave from central NC. Not sure whether to go up and across first--that is across Iowa, Nebraska, etc. Or go down and over through Arkansas,OKlahoma etc. Or neither! Musts are the Grand Canyon, Yellowstone(should we?) Sedona, the Black Hills. Very interested in two lanes. I don't feel we have the time to do CA so I thought we would go from Arizona up (or down) from Yellowstone. Planning is overwhelming me. Should I book compgrounds/motels ahead of time? How do you decide a time frame? What kind of gear do you guys suggest? Geez, I need lots of help...this is just the beginning! Thanks!
