It can be fun, but you wont do much "hunting" on opener in a public field. Everyone just sits on buckets or stands in the field and pass shoots at the birds. Dont get frustrated, youll see some crazy stuff. Youll see blackbirds, blue jays, finches, killeer, hawks all shot. Guys will be standing out in the open in blue jeans and a white shirt spooking all the birds, while shootint at them 50-80yds out. It just is what it is. If you can luck out and avoid these people it is fun.
Youll need to register for HIP online first before hunting dove.
