I think Ale Asylum's Bedlam is pretty fantastic, but they don't distribute outside of Wisconson as far as I know.
Then I'm not interested...hehehe, just kidding. =) I am going to make it my mission to find the best Belgian IPA.
Actually- - Green Flash's Le Freak is quite good. And Nebraska Brewing Co.'s Hop God was just an insane beer so maybe the style does have a few bright spots.
Mischief from The Bruery is great. They don't call it a Belgian IPA but I tend to think of it as one since it has all the elements.
