It has been an issue for a while. I cannot believe it hasn't been on the news more. It looks to me like there haven't been enough deer havested in the past, and they are overpopulated. That is natures way of thinning out the weak since man doesn't do it. I am not sure how I feel about slaughtering all of them on site though. It seems like it would be a case by case basis. The slaughter may be too little too late.
