This year the show was bigger than in past years, though still every bit as disorganized. They don’t make money off of it, and as such they don’t dedicated a whole lot of resource to it, but if you know when and where to be, it’s an awfully good show.
This year they were using 5″ mortars, best I could tell, and they looked amazing. Best show I’ve ever seen there.
In 2018 and beyond, check them out if you’re in Auburn, Washington, because they pour a hot bucket of money into it, even if they let the logistics slide pretty much unchecked.
