I have seen countless numbers of them, unfortunetly it has been in a bad manner. There is a labratory close to my town where they released them many years ago and they roamed the premises for years and breeded and numbers went through the roof because the area around is all forest preserve and is not huntable. A few years back they hired so called "sharp shooters" in whom they paid to come harvest deer off the property and drastically reduce the herd count.
