That's all from breweries I've heard of or beers I've had. I'm sure there are some I skipped over, but some of the best beers I've had at these fests are from breweries I've never heard of and have no line. Also, don't feel obligated to drink every pour you have or the entire pour you have. A lot of beers aren't going to live up to the hype or be worth your time. I usually treat it almost like a wine tasting, swish, maybe swallow a little, then spit. Even if you only take small samples, you'll get hammered quick trying to check off every brewery or beer on your wants list. Have fun!
