How about four corners?
How about starting on the coast of Maine, across the Great Lakes to Oshkosh, Glacier National Park, maybe Yellow Stone then hit something along the northwest coast of Washington. Then down the coast to San Diego. Then start east, Yuma, Tucson, Corpus Christy, New Orleans, Gulf Coast then head south for Key West. Then back up the East Coast. One advantage of this circuit is the ridges aren't the Rockies of Colorado or California Ridges.
Great aviation history all along the way.
Hope it is something like a Champ or Cub. But, a 172 is good. Fly low and slow and enjoy the journey. Oh and take a good video camera and make a short movie out of it. But, first write a book about the adventure.
Years ago I flew a Champ from Arizona to the east coast. Camped out overnight at a lot of small grass strips. Made lots of friends and loved it. Av gas was about fifty cents a gallon. Never got more than 3000 agl. Got passed by some trucks in Texas, I had a ground speed of about 35 knots. Landed got a tour of the Money factory and waited till the next morning to continue.
