I agree with most of the reasons given, farming practices, varmits etc., but think that those are reasons why we never had a big population, not why they have become extinct, at least in the SW part of the state. I gotta believe that the final blow was some kind of disease, like what has happened to the honey bees. You'd think the game commission would do some reasearch and let us know, unless like Dusty Ed said, they are the ones responsible.
