Well Cape, you missed it this year, it was this past weekend.
That said, I went to the Saturday afternoon session, and it was a blast. The line for buying tickets and the line for having tickets to get in were about 100 yards long, but moved reasonably quickly, and there was plenty of space inside the area. There were definitely more breweries this year than before, so it people distributed out pretty well. I avoided the places with the longest lines easily - why do I need a sample of Sam Adams, Magic Hat, Long Trail or Harpoon? I can buy those, and have had 90% of their offerings. Going with the small breweries gets you faster service. A couple of places like Hopfenstark didn't have any lines when I was at their booth.
The real trick is to get a sample and find a new line BEFORE you start drinking your sample! There's no need to mill about in the center drinking and stand in line with an empty glass! I easily used all of my tickets, and three of my friend's because he's not used to ~40oz in one afternoon. It's about pacing, food and water.
I forget who had it, but SOMEONE had a Black Spiced Wit, that reminded me of Biermuncher's Wit with some roasted barley. Oh man that was good.
