I'm biased of course, but I have traveled all over this great country, and experienced a lot of places. Raleigh, NC has been fantastic for our family. We live in the County (no city taxes), we're 10 minutes from a growing downtown, 1.5 hours from the beach, 2.5 hours from the mountains, and the business climate both for large and small businesses is stupendous. Raleigh is routinely voted top 10 places to live and has won the US World and News rankings twice, I believe. NC gets a bad rap for education, and it's not always unwarranted, but Wake County (Raleigh) is one of the best school districts.
We do have mild winters, and brutally humid summers for about 1 month (mid July to Mid August). If you have bad allergies be aware of pollen season every year, which turns everything a hazy yellow for about 2 weeks. But from March to June and September to November, it's always very pleasant.
As an unbiased opinion, of all my places of travel, some of the nicer places:
Texas (But brutally hot in the summer) - Best political atmosphere for me
Florida (But brutally humid in the summer and hurricanes) - Best climate for me
Arizona (Also hot) - Best people
New Mexico - Prettiest Scenery
