I think the legal liability is a big factor. You can do everything perfect, but if someone gets hurt, you're hiring a lawyer to protect yourself. Win or lose, you still lose.
I swear, if I won the lottery I'd buy a few massive pieces of property in the Mississippi floodplain and I'd build a wingshooter paradise. I'd shoot doves 3 days a week from September till January. The other days would be for quail and dux.
I'm glad and lucky my family decided to start having our own dove hunts again the last few years, we have 3 different afternoon hunts in 3 different fields. Always a lot of family and friends everyone knows how to hunt and be safe, all the kids including mine runnin around picking up birds it's a great time. Usually everyone gets there limit pretty easy.
