Boulevard Wheat was one of my best standby beers before I moved to Colorado. However, their distribution hasn't quite made it from Kansas City yet.

However, after the move, I have found plenty of new local micro brews to try.
1) As mentioned before numerous times Fat Tire is excellent, but being a wheat beer lover, Sunshine Wheat (another new belgium brew) direct from the brewery is quite delicious.

2) I'm more partial to the Odell's lineup. Odell's is yet another Fort Collins brewery. (90 Shilling/Easy Street Wheat/Double Pilsner) but you can't really get that outside of a couple state area around Colorado.

My general rule is that the quality/taste of the beer is inversely proportional to the size of the brewery and the distance you live from said brewery. That being said, there are exceptions to the rule and some bigger breweries do produce some decent drinks.
