We drove from Jacksonville to Arizona (so far) over the last month. Places we stopped: St. George Island state park (FL), Fort Pickens (N Seashore - FL), Palmetto State Park (TX), San Antonio (Traveler's World), Big Bend National Park, Oliver Lee Memorial Park (NM), City of Rocks State Park (NM). We will be going to Usery Mountain State Park (AZ) and Sedona (boondock) in the next week or so.
Had we taken a bit more time, I would add Bayou Signette (LA), Catalina State Park or Kartchner Caverns State Park (AZ).
There is quite a bit of boondocking in AZ. check freecampsites.net.
