I recently read about a guy in Michigan that runs spots on a sports radio show in early Spring to try and attract prospective umpires to come out. Apparently, he runs little spots called "Stump The Ump" that fields questions from sports fans as a way to gin up interest. What other things do you guys do to boost your numbers of umpires? And more importantly, after you have them in the door, how do you keep them around from season to season?
