Some claim deer are smarter than they're given credit for. My wife swears that during hunting season they somehow manage to find there way to places where there is no hunting but maybe it's only the survivors. Of course, these are suburban deer, who I suppose have their own habits. Those that live in the city naturally are a little different and they don't worry about hunting. There is some hunting in the suburbs around here.
The only time of year deer are routine on my 5 acre nearly rural place is about when pre-season scouting begins... Otherwise it is not so attractive with the dogs etc... feeder be danged...
