We had an over-abundance of deer and plenty of good bucks long before MO instituted APR. This is the same game management system that brought deer heard back from almost nothing after the Depression.
The APR bill of goods was sold to MO hunters primarily on the premise that in years to come, we would have trophy bucks to compare with those in Kansas and Iowa.
In the end I think it comes down to whether you think more regulation is the answer to a contrived 'problem'- or that Joe Regular is an idiot because he shot a forkhorn that he actually has a tag for.
I'm inclined to think if a man hasn't gotten his point across in 4912 attempts, 4913 probably isn't going to do it.
