Goose Island Root Beer

I am a huge fan of root beer.  Always looking for something different, local and new to me.  Now, my constant is IBC root beer, you can't go wrong with a root beer company born out of prohibition!  Since living in Chicago, I have come across Goose Island root beer.  Chicago's answer to root beer, and its pretty good, has a hint of vanilla and is pretty mellow!  Not too shabby.
