In 2012, the American Plainsmen Society will be holding its first of what I hope will become an annual event. This will be in October, near Kansas City. I'll post more after the first of the year, and as details become available. We will be doing some postal matches in 2012, as well.
In the interest of clarification, I should probably point out that the American Plainsmen Society isn't related to SASS in any way. It's an entirely separate entity.
Best,
Caleb
