Ill be check out North Country Whitetails site next month. They have alot of big names backing (Bio Logic, Foulkrod, Alscheimer(sp?), etc.).

The deer management part, I agree with TC. It will be hard to " manage" the selection of deer on 40 acres. However, I believe that it can be improved, espicially if the deer are more enticed to stay on the parcel for longer lengths of time, which is what you are trying to do.

Hope it works!!
