Flight around the lower 48

I've been thinking of taking a solo trip and the idea of flying around the country and landing in each state (lower 48 only for now) keeps popping up. I've got friends and family scattered from coast to coast so I'd have lots of places to stay for a couple days and visit.

Starting and ending in FL, I figured I'd hit the East first, heading North, then head West. I fly a PA-28-181, which is reasonably economical, cruising around 115-120 ktas @ ~9 gph. FF shows preliminary planning @ over 8,400 nm, 74 hrs flight time and 670 gal. I'm sure everything will come out more. Should be quite a trip.

There are some stops that I will definitely make in order to make visits, incl; KFHB, KHXD, KILM, KDMW, KRNT, KVUO, KEMT, KGEU & T31. There are some other stops that I am thinking of, just because I want to fly or visit there. These include KSSI (for BBQ), KFFA (First Flight? Of course!), not a landing, but flying the Hudson River Exclusion, Overflying Cape Cod and Niagara Falls, KUAO in OR to visit the Vans RV factory, KNEW because it's New Orleans. Otherwise, I'm very open to suggestions. I'd love opinions about alternative routes, must stop/see places along the way or worthy of a diversion, airports with camping as well as places to stop for a more active overnight, etc... I'm retired, so I have plenty of time, which is good as I expect this could realistically be a 4-6 week trip. I'm thinking next Spring would be a good time. Planning VFR for now, but hope to have my IR before this starts.

VERY preliminary basic route is below... Looking forward to comments!
