Flour bombing experience??

[tomhurley]

Our local aero club is planning a flour bombing (2 lb bags of white flour from 200' AGL) competition next month. My question; how to best drop it from a Cherokee 180. I see two options, either out the pilot side drop down window or have a passenger nudge the door open.
While I appreciate all opinions what I'm really looking for is info from someone who actually has done this.

Thanks.
