I'm glad you enjoyed it. From a Busse availability perspective, I'm blessed. Knob Creek is within a half hour or so of home, and they've had an outstanding Busse selection the last couple shows. It's strange -- the main event is a machine gun shoot that happens continuously right beside the (open walled) shelter house where vendors set up. If you come, bring hearing protection because it's loud. There's a firing line cutting loose with full-auto pistols, sub guns, AKs, ARs, M-60s, M2 heavy machine guns, and even a mini-gun. It's loud and very interesting to watch.
Seemingly out-of-place among tables of Military surplus gear, t-shirts, and flea market wares, Busse sets up several tables to sell high end knives. The shoot draws a crowd where, if they say an Argonne Assault LE is "11-97" some folks think they'll get change back from a $20 bill. However, it also draws the faithful from the surrounding countryside; we know the difference between Busse and Flea Market blades and come to embrace the good steel into our lives.
I went to one of the Indy 1500 shows. It actually had a much wider range of knives to buy, and they had guns for sale (I bought a Stag Arms lefty AR that trip). I don't recall seeing any actual guns for sale at KC (they've got parts and de-milled rifles, but since there's no phone lines/internet connectivity, they can't run authorization checks). Still KC has a much larger Busse presence and it's much closer to me than Indianapolis, so that's where I'll be in less than two weeks.
