Just got back from Ashville. In the downtown area they have about 8 (or more) micro breweries within a 4 block area (Green Man, Burial, Wicked Weed to name a few). I'm not a big beer drinker, but the breweries are a blast to visit. Good food, beer (obviously), music and atmosphere. If you want bigger craft breweries they have New Belgium (#4) and Sierra Nevada (#3). On top of that its a really cool city in the mountains to visit.
