EVERYONE should go look for one new person each year and bring them along...for the ride. Offer to give them a dog to "run" in the puppy or derby stake. Let the judges and bracemates know they are new and HELP them! Get your kids on a horse, wheeler, or put a leash in their hand and a whistle around their neck (kids LOVE to make noise) and they will be begging to go with you when they get older.
Get items donated and offer a free raffle or just GIVE an item to the newbies to keep them coming back. Talk to them, talk to them, talk to them!
Put free trial or training ads/notifications online...craigslist...forums and PROMOTE your clubs.
Host raffles - which reminds me...I have tickets for you...
