I hear Black Hawk Farms will be moving the T2 guard rail back to the fence line. Unfortunately I think managers of Blackhawk should think very long and hard on what they are doing and why. I don't think the fence line is far enough back. They should take out 50+ feet of the forest trees as well. If your going to do it do it right!
