Here in Fort Collins two of the 8+ craft breweries operating in town are about 100 yards apart. We had guests and went as a party of six to brewery #1, sampled 18 beers, then walked to the next and sampled another 12 beers. (Fortunately all in about 3 oz glasses we passed around). I'd never tasted 30 beers in a little over 2 hours. Fortunately these are less than a mile from home, and I drove home quite carefully.
