Museums on wheels are hitting the road across the country to celebrate America’s 250th birthday. This summer fairgoers at the North Dakota State Fair can take a step inside American history at the America 250 Freedom Truck from July 17-25.

The exhibit tells the story of how the original 13 colonies declared independence and secured American sovereignty 250 years ago. The interactive exhibit is built for visitors of all ages and features a quiz, a kiosk to digitally sign the Declaration of Independence and a wall of 50 American heroes.
