I'm going, friends with a guy that works at Big Rock in Birmingham, we go anyway. lot of complaints about it being outside in the winter, but you can't complain if you don't go, it could be good. You usually get a cup with 10 tokens, each token gets you a "taste" usually by your 6-7th, your pretty "toasty" You can buy more tokens too. Best is to get there early cause it packs up later in the day. Mich Brewers guild members get in an hour earlier too. It's "different" a good time, mostly find new breweries in Mich with good beers you want to take trips to later on.
