The Edmund Fitzgerald is one of my favorite porters. It's rich, dark, roasty, and full bodied. I love it! I haven't been able to get Great Lakes beers around here any more- the stores must have a different distributor or else the distributor no longer carrries Great Lakes. I like all of Great Lakes offerings- they make a wonderful APA called "Burning River" that is another favorite of mine, as well as an IPA called "Commodore Perry".
Ohiobrewtus posted an Edmund Fitzgerald clone recipe a while back, and it's really good!
