I am taking a looooong trip from NY state to southern california and back next year. Any suggestions as to great sites to see along this route. Do not need campsites for this trip, just memerable places.
Also would be remiss for not saying visit the best duty station I ever had in my 32 years in the Navy "USS Midway" museum in San Diego. Lots of history in regard to that ship.
Also a nice place to R&R in California is Warner Springs Ranch close to Mt Palomar Observatory. Actually close to alot of neat things. My uncle lives in Warner Springs we had a family renunion their (ranch) a couple of years ago had a great time be forewarned no TV's or Phones which I loved and kids hated.
With June July in mind, Think I would go to the north for the national parks, then swing down the coast of Wa Or Ca, then on the return stay kinda north central for the national parks. Driving straight through to the western parks as a shorter trip could be made later nearer NY. WOW just reread the OP 4-5 weeks 300 miles a day 20 days driving, 15 days for sightseeing, very fast pace. And remember its two nights in a stop to see one days sights.
