Graydawg,
First off, let me say thank you for your service to this country. My buddies and I were in the Niobrara river valley turkey hunting this last spring. We stayed in the little motel in Niobrara and hunted on the Indian reservation. It is without a doubt some of the most beautiful country up there. We are going back in October. We saw hundreds of deer and turkeys in the three days we were there. If you are going to be hunting the reservation send me a pm and I will let you know about some spots that we saw alot of deer.
