Bruce asked for some east of the Mississippi destinations, so here you go!
We were in Bar Harbor, Maine, last week in the 980. Fantastic place-- we stayed in a beautiful hotel on the waterfront, and my son even talked me into getting up at 4:30am to climb (okay, walk up) Cadillac Mountain for the sunrise.
Acadia National Park was lovely as well, with some beautiful beaches.
The only issue was that many restaurants and such were closed, or starting to close, for the season. Still, a great time to visit up there.
