Ed,
Can you hit one from 40 yards??? that is how far the shot was on this one. It would be a challenge, like any bow hunting I guess, but very possible. There was a fair amount of cover for stalking. There was alot of water so I don't know if sitting on water would be very productive. I did see lots of bucks so at least you would have multiple opportunities. I know he has never had bow hunters and it would be good for him to have guys like you that understand bow hunting and how difficult it can be. Call him again.
