Much of the West was built upon mining. Idaho isn't much different from Arizona with the exception to the minerals mined. My grandfather was a miner, and even my dad spent a year in the mines. We took the Sierra Silver Mine Tour in Wallace with the kids. I thought they would be scared of the loud sounds, and cave-like environment, but they loved it. They also enjoyed getting a few scoops of ice cream after the adventure. The mine tour is a must-do if you travel to Wallace, Idaho.
