1. Holden Beach, NC: Beach, warm but not too hot. Small town of Shallote 10min away, Wilmington 30 min away
2. Asheville, NC: Warmer winters than Indiana, but not hotter summers. Mountains, lots to do.
Thats about it, I've visited lots and lots of places from Booth Bay Harbor, Maine (hated it) and Tucson, AZ (liked it, but it was Nov not July) to Lake Tahoe and NYC. All had some things I liked (except Maine). But all had significant aspects that I didn't like well enough to move there such as weather, cost of living, local population, etc.
