Oahu,
It's tourney time here. Duke, Carolina, and NC State are all within 15 miles of each other. So, it's nuts. But the academic levels are high. The RTP has a lot of high tech business and there are a lot of bedroom communities.
While all that sounds happy, this area is a bit busy.
Surfing is lower middle in interest. There are lots of mono hulls sailing. Lake sailing is windless in the summers, IMO. (You have to really love sailing to sit in a Flying Scott in one of the regattas here. Not me.) You would really have to get used to weekend trips and their expense instead of day trips, too, I would think.
I understand the cost of living question, but the quality of recreational life may be a farther stretch than it would appear. But it's possible. If you fly up here, have someone drive you to downtown Raleigh from Durham or Chapel Hill on I40 around 5 p.m. The geniuses that work at RTP are wild animals in BMWs and big SUVs. Check out
