To enter, put a comment on our original post (not this post) by this afternoon at 3pm EST telling us what your favorite drink for Brewfest is. You guys all went with the "in-game" idea, which is fine, but personally, I like drinking out of game a lot better than in-game (in-game drinking just gives me a headache). So for me, Jack and Coke is the drink of choice. For beer, definitely Fat Tire with a meal, or Guinness if it's just a pint at the pub.
But good luck with the contest! Official rules are here (short version: must be in the US and 18 or older, one randomly selected comment will win and you can only enter once). Happy Brewfest!
