The following disclosure is from Allegheny Park's web site regarding Saturday's Turkey Shoot at Deer Lakes:
Fee: $10/members, $11/nonmembers
All skill divisions offered. 18-holes and a bonus 9-hole final. Divsions will be randomly mixed so players of various skill levels will have the chance to play together. All divisions play white tees during Mixer events at Deer Lakes Park.
So....there you go.
Have fun with that bonus 9-hole final, everyone!
