This sentence really makes me rethink how much time some people routinely spend on the road. I live in Santa Monica where's it's minutes away from beaches and about half an hour away from mountains. If I just want to go there to relax, I don't want to have to spend hours just getting there.
Also, as someone from NC, I'll go ahead an say while I'm a big fan of the dramatic scenery of the West, the coastline and beaches of NC have their own special charm, not to mention are cleaner. Only problem is, with sea level rise, the Outer Banks probably won't exit in a couple decades.
I guess it depends on what you are looking for though. For my tastes, I love parking off of Reedy Creek Road behind LCCP, and being able to ride Crabtree (fast, "flow" trails), 286 (slightly more technical than the crab), Rocky Road (very technical and challenging), Sludge (technical in spots), and then go grind out some training miles on the gravel roads in Umstead.
That said, I'm sure there are places with even more variety. But I've never suffered from a shortage of places to ride here. :-)
One thing I really like about this area is that for a moderately sized urban area, there is a lot of nice outdoor "green space" with trails for hiking, running, and biking. Yes, if you're into MTB you're basically limited to just XC here, as we don't have the elevation change for true DH riding... but again, there are mountains about 3.5-5 hours away and you can get your fix of DH stuff there with a day-trip if needed.
It's also nice having nice places for water sports / water based recreation... you've got Jordan Lake, Falls Lake, Lake Crabtree (just don't eat the fish...), Harris Lake, University Lake, Cane Creek Reservoir, and the like.
And as others have pointed out, there are plenty of educated people here to contribute to the intellectual scene. Obviously there are the folks at Duke, UNC, and NCSU, but don't underestimate the impact of the smaller, lesser-known colleges and universities in the area either. Take NC Central, for example. They're a small HBCU located in central Durham, and have a VERY highly regarded law school for such a small school. I routinely meet people from all over the country who come here to attend NCCU Law. And you also have Shaw, Peace, Meredith, Campbell, St. Augustines, as well as Wake Tech and Durham Tech, all contributing to the base of educated people in the area.
