Officially, the states I have remaining to visit are: Hawaii, Mississippi, Louisiana, maybe Arkansas - can’t remember, Maine, Vermont, Rhode Island, Connecticut, Delaware. I’m not sure I’ll ever tag the NE - or Hawaii as they are not overly important to me. Would like to ride the Natchez Trace and the Blues Trail. Getting to the Ozarks is pretty high on my list too. Edited to change: Idaho was originally on the list but I had in fact been to West Yellowstone years ago which is in Idaho. Recently we traveled (by car) from Salt Lake City to West Yellowstone - stopping along the way in Pocatello.
