In CFDA, the World's competition normally signals the end of that years competition season. World's is held the first weekend in October every year, but that doesn't mean that the clubs quit shooting, or holding matches. The autumn and winter mark the time for invitational shoots. A club will decide to hold a shoot, send out the information, and folks come to participate in the event.
Tomorrow, the Big Thicket Bushwackers are holding an invitational shoot to celebrate Halloween in their particular style.
In two weeks, my home club, Thorn Valley Shootist Society, is hosting our invitational and we'll talk more about that as we get closer to that date.
