As someone who used to try and manage a few small private spots for dove, I can say it's tough. My experience is that you can only get at most 3 good hunts(with declining results on each successive hunt) out of a spot before they get spooked. We would hunt only about 45 minutes to an hour and get out. That still didn't help. One spot that didn't get managed at all got pounded opening day. That was basically all the shooting you could get out of that spot. The birds aren't dumb. When they get shot at they move somewhere they aren't. I give the PGC kudos for trying to provide opportunities, but it's tough to "create" a dove field that will benefit hunters for an entire season.
If I wouldn't get arrested I'd hunt on my roof. Could probably manage a limit with all the birds zipping around to the neighbors feeders.
Remember, shoot straight and shoot often.
Good... Bad... I'm the guy with the gun.
