RE: Hunting in the parks
You should have some great opportunities because they don' t open these areas like this unless there' s an overpopulation of deer in there. Your biggest obstacle will probably be trying to overcome the temptation to shoot the bucks that you' ll probably see (given the facts of: the RUT, the deer are mature and less concerned about people, its IOWA!)
However, the deer will quickly find out what you' re up to and you' ll find that deer that show no fear of walking around in people' s back yards with people nearby will turn into skittish creatures when you set foot in their territory.
