When visiting my Mom and Dad in northern Mn. In the early 90’s when the boys ..William, Denver, Daniel Were little we always looked forward to going a little further to the Sudan mine. Going a half mile in the ground . Riding a trolley cart to learn about how the men worked so hard and had to deal with transportation to the work site. 35 Years later we still talk about it and the giant mining trucks.
