Have very public promotional events in which you invite children interested in playing golf team up with your golfers for a childrens tournament, just for fun and learning.. Inform local news media of your plans.

Get promotional sponsors and advertising sponsors for your events. Promotional advertising agencies (Google search that) sell products that businesses use in advertising like WGA pens stationary, stickers, coffee mugs and may give you or direct you to event guidelines etc. League jackets  and stickers, automotive emblems and membership status levels all help to bring your group into a higher level of public attention. Go Big! It’s fun and so much better than being bored. 

Guess you could do like the men do haul around beer and drink it all day and run around in your golf carts?
