I'll do you one better nodog, start knocking on a few doors of property owners adjacent to that park and I'll bet you get yourself some permission. I live in a somewhat yuppy neighborhood that has a "protected nature area", it'sonly protected from development, not from hunting. Many of my neighbors have seen me hunt and trap the area with success. Except from the most extreme yuppy, I been told thanks, those deer and killing my landscaping, shrubbery, ect. Look for the homeowner with a full size truck in the driveway.
