I know this is an old thread but Tasmorn the circles you see on Google Earth are line-control flying fields. And like you I haven't found anything of value at City Park yet. The flying fields were used as a staging area for FEMA after Katrina. There is a club that meets there on Sunday afternoons. I thought about hunting it but didn't figure they would appreciate me digging up their field even if I did fill all the holes in. As far as the woods go I wouldn't mind hunting it or the road going to the flying circles, but would definitely rather do it with a partner or a group. I was thrown out of the circles years before because they weren't letting anyone go back there due to and I quote, "Guys going fishing there without fishing poles."
