Funny, what a coincidence. When this deal first came out, I was thinking of doing Miami neighborhood store to ATL up I-75 along FL's Gulf Coast. From what I've seen (SRQ) and heard, the FL Gulf Coast is very different from its Atlantic Coast, both geographically and culturally.
But I had already booked my annual roadtrip for this year: NY to Maine in mid-May, up I-95, with a National free day. (Hopefully the weather will be nice, and the time I'll be there is the last week before the rates significantly increase at the PWM Motel 6. The $18 JetBlue Travel Bank credit because of today's 1 day sale made it even better.) So the FL Gulf Coast roadtrip will have to wait for a future year.
