Sentinels day in Missouri?

Anyone know a place that is doing sentinels day in Missouri? Looks like my flgs dropped the ball, which sadly I am not surprised.

At a guess, you ought to be able to find someplace in the Sentinels world headquarters in St. Louis, no?

been trying but haven't hit on the few places I know of in Missouri having it yet and St. Louis is a far enough drive I can't just go there without a plan
