The largest city in Montana, Billings has just over 100,000 residents. Nicknamed the Magic City, it is located in south central Montana. The city has numerous attractions including an extensive park system with jogging and bike trails, cultural institutions like the pictured Alberta Bair Theater, and several colleges including Montana State University-Billings. The city is growing and the economy unusually strong thanks in part to the Bakken oil play, what has been called the largest oil discovery in U.S. history, as well as the Heath shale oil play north of Billings. The Yellowstone River runs through the city, and there are 6 mountain ranges in the area, including the Bighorns.
