This was on tap at Montana Ale Works in Bozeman, Montana. It was a pretty solid wee heavy. It wasn't as good as some of the other wee heavy's I've had, but I'd say it's up in my top 3 in the style. This one is definitely one you should try if you can find it anywhere. From their website, it looks like you'll pretty much be out of luck unless you happen to be in Montana.
Check out the brewery's site for more info.
See if it's distributed near you and what others think at Rate Beer.
