OK, so close the park one morning per week, and open it for bow-hunting. Arrows make no noise, and have limited range, making them much safer than shotguns. Plus if you do it from tree-stands, any misses will just go into the ground near the goose.
Good idea, Sauron, but way too practical for the bureaucratic mind to grasp.
I was part of a group of hunters that made a similar proposal to our City Council to deal with the excessive deer population in the suburbs. The local politicos wanted to spend public money to hire "professionals" to cull the deer herd in the local metropark system. This seemed like a waste of money, considering they had bowhunters in the community already licensed and qualified to do that, who would probably even spend money for a permit, as opposed to expecting to be paid.
But that was just to skeeeeeery for some locals, many of whom clung to the notion of just "catching the deer and taking them someplace else".
Anyway, they didn't like the idea of hunters with bows and arrows in the parks, so instead they close the parks early a few nights a year and have the locals cops (on overtime, of course) cruise through the parks with a spotlight, jacklighting them using AR-15's from the back of the pickup truck. They give the meat to charity, at least. Seems stupid though.
Oh yeah, sorry to get off-track. We got the same problem with geese, though~~~;P
