Breweries of the United States

So I came across this really neat poster showing all the breweries in the U.S. and thought I would share with the group. The poster itself is $30, and would make a great talking point in any home! Here is the website I found it on.
The concentration of breweries in the Central PA area is incredible! We should really plan to visit one (or more) of these breweries as a group some time soon.
Go forth thee seekers of the brewed barley, with thou pint glass in hand!
