I agree with BMAKJ. Run a tournament for the rec teams, but I would add that mid-tournament invite in two high level comp teams to run a exhibition game on one of the fields when most of the rec teams are on site on Saturday . See if the coaches from the Comp teams would let some of the girls from the rec age group be courtesy runners for the pitchers and catchers via a raffle open to the rec age group players that the comp teams are. I would recommend 14U comp teams as they will be about the average age for rec attendees. The rec teams would get tournament experience, you would get experience running a tournament, and the girls get to see an exhibition game. Win, Win, Win
