There are few places that will give you a better perspective on life than a walk through a cemetery. One in particular can also give you a different vantage point on history as it's the eternal resting place of legendary explorer William Clark among others and it's located in St. Louis, Missouri.
The St. Louis man was in command of Fort Clark, which later became Peoria, Illinois and was part of the Yellowstone Expedition which led to the founding of Omaha, Nebraska.
