Mention the word 'Medora' to anyone in North Dakota and one thing will likely come to mind - the Medora Musical. On May 20, the musical came to Bismarck in a very unique fashion. 

Coffee drinkers at Barnes and Noble were treated to a special performance Tuesday morning when the Burning Hills Singers surprised them with a flash mob sneak peek of this year's show.

The musical is considered 'the greatest show in the west' and is performed among the rugged terrain of the North Dakota badlands. The show kicks off on June 6 and runs every evening through September 6. Tickets are $35 for adults and $16 for kids. Visit their website for more information.
