If you were one of the guests of the gala event to celebrate the opening of the Lewis & Clark National Bicentennial Exhibit, you would have stepped right off the streets of Philadelphia into 19th century Illinois.

Guests dressed in period attire and enjoyed a variety of food and fun during their stay in the past.
