It is Blot Out the Sun indeed! My love of FFF is no secret, and we made the short trip down to the brewery for the afternoon. This particular beer was interesting -- very hoppy (even on nitro, which for me typically diminishes the hops), with a lighter body than one might expect from an imperial stout.
One other very special treat that we had was Zombie Dust on cask instead of kegged. The profile is actually different enough to notice (though clearly still the same beer), but still superb.
