On a gray September morning, a group of us visited the Big Nickel and Dynamic Earth in Sudbury. The Big Nickel, Sudbury's most famous landmark, is a must see - after all, mining of nickel and other minerals are what built the city and the region. Dynamic Earth, a museum that explains the history of mining in the region, is located next to the Big Nickel. A tour seven stories down into the mine shows the different methods of mining over a long period of time.
