Yeah, but I don't flag Roy's posts despite that.  He has the same right to discredit himself as anyone else, even if he overuses it.

As for feral animals not going away, part of the problem is misapplication of the one methodology that has been historically proven to work.  Unfortunately it's been used against native species more often than not, such as wolves in the lower '48 (eradicated in seven years), great auks (the original 'penguin') and passenger pigeons.  These were numerous, widespread species.

But the most extreme example is the Rocky Mountain locust (Melanoplus spretus).  Check that one out.
