I don't want this to sound bad, but come on, the kid is handicapped. Do you really want to kick them out of a place to hunt? I'm sure that his dad likes to "hunt" once in awhile, too. My kids aren't handicapped, but when I take them fishing, very little of my time is spent fishing. It's spent tending to them and their needs.I can only image how mucheffort that his dad id putting out so his son can enjoy time in the field.Like I said, I don't want to sound like a jerk, but if they aren't causing you problems with poaching, spooking deer, etc.....IMO, let them be.
