I sometimes try to pick a theme at big beer events. All Sours. All Lagers, Weirdest thing on your menu, etc. At GABF, I like hitting the breweries that nobody heard of. You can really find some gems. "Uncle Billy's Brew and Q" one year, for example. They ended up with GABF bling for a Kellerbier or something that year, and everybody walked right past their booth. I'm sure glad I stopped.
