American Freedom Train Crosses the Stone Arch Bridge, Minneapolis, 1975 (by Steve Gilschinski)
The American Freedom Train, a rolling museum of U.S. history, had its big Minnesota photo op on August 31, 1975, when it crossed the Stone Arch Bridge in Minneapolis. (Remember when trains rather than Nice Rides and stroller-pushing hipster parents used this thing?) The Freedom Train visited all 48 contiguous states during its 21-month commemoration of the nation’s bicentennial.
