In N.C. R-D would have the high tech opportunities but the other two would have small town lifestyle opportunties depending on whether you preferred mountains or shore.In Fl. Gainesville is nice college town atmosphere with good cycling but job opportunities might be limited to university related.The South Beach area of Miami might give you some video type opportunities if you like the more urban atmosphere there .There are a few spots where Mtn. bikers talk about in Miami but overall it is not particularly cycle friendly (though I like cycling around South Beach when I get down that way).As to Jacksonville I'm not particularly impressed with the urban area I'd prefer to live somewhere near there such as St. Augustine if I lived in that area.
