In order to have a healthy herd, the buck:doe ratio has to be kept in check, so not shooting does really doesn't help grow bigger bucks, unless the ratio is way out of whack in favor of too many bucks, which i highly doubt is the case. Later in the season there may be some validity to the statement, as the mature does could be carrying the next booner, but even then too many does isn't good for the herd. This neighbor sounds like he has no clue about herd management. What it comes down to is that you were happy and so was the landowner, thats all that matters. unfortunately, the neighbor can do whatever he wants on his land, as long as he's following the law. might want to check in with this guy in 4-5 years and see how many big bucks he has on his property and how many basket racks he has hanging in the shed!
