You might be surprised, but I think you should add Montana to that list of states where it would be hard to pick. Montana is behind only Oregon and Vermont when it comes to breweries per capita, and those leads are dwindling. I had no idea before moving here, but the beer culture is ridiculously strong. I live in Billings, MT, and in this city of 109,000 alone, there are seven breweries and two distilleries. Six of those breweries and one of the distilleries are located in a five block radius.
Anyway, back on point, I would love to see one of the larger Montana outfits make it into the festival. The Harvest Moon Brewing Company out of Great Falls and Red Lodge Ales out of Red Lodge both have the capability to output enough of one of their flagship beers to qualify, and I think people would flip over their offerings. And, they both make and bottle/can very good Scotch ales (Harvest Moon's is called Loch & Lode and Red Lodge's is called Jack's 90).
