When my wife and I moved back to WI, we just started hosting tournaments on the third Saturday of every month. That way it was a consistent schedule. Sometimes it was just us and her brother, but now we have 10-15 other people every month! It has taken us 3 years to get to this point, but the consistency was what did it for us, along with having them be official so that people would see them online. We tried talking with two youth groups and got the permission and support of both youth pastors, but that didn't go anywhere...
