No doubt. And without any reservation whatsoever, I would encourage anyone who would be happy with him to shoot him with their first tag or their last. But a lot of guys will also do exactly what you did. That scenario probably plays out several hundred times across the state over the course of a season, and thousands of times over the course of several seasons. Without question that leads to the survival of a lot of "decent" bucks (most of them young) that would die if that second tag wasn't also the last tag.
So if older age class and bigger deer is a priority, the limit helps. I'm not sure that should be the priority from a statewide management standpoint, so I'm not here to trumpet the 2 buck limit. It definitely benefits my personal hunting style/goals, but I'm undecided on it philosophically. Both sides of the argument have merit. I was just making an observation that this is a good example of the limit in action.
I've never "tagged out" on bucks. The limit has had no affect at all on my deer hunting decisions personally. But I think it would really suck to be done the first week in November, so I don't think you'll regret your decision on this one.
