How about Pigeon Shooting with the Wiz?
The back part of the stepped area at the front of the grandstand and to the left is covered in pigeon crap that is about 3 inches deep.
Charge $20 for 6 shots plus a photo with the Wiz & your bag.
Here is The Wiz pictured with local identity Mark 'The Silver Fox' Read after a successful shoot on a vacant lot out the back of Bankstown Square.
