You might want to think of starting regional events or get togethers.
I had a successful one at my old place for another board, we had 46 people show up. A great chance to meet new folks that are as nutty as we are about the mutts. The weekend lasted three days with cookouts dog training at my facility and a whole lot of fun!
I am in Oklahoma, and would be willing to host a training day for anyone interested. We have plenty of land, birds and training doo-dads!
