Business Insider has published their annual findings of the 25 Most Hungover Cities in America, and three Montana cities landed in the top 10 (two of which were in the top five).

Business Insider has once again established who (or where) in America has the biggest drinking problem.

Our two main sources were the Centers for Disease Control and Prevention's 2011 and 2012 Behavioral Risk Factor Surveillance System, an annual survey of Americans' health habits, and the Census Bureau's 2013 County Business Patterns program, which tracks the number and size of businesses in counties and metropolitan areas across the country.

The study looks at those who admitted to heavy drinking, those who admitted to binge drinking, bars per 100,000 people, beer/wine/liquor stores per 100,000 people, and alcoholic-beverage-producing establishments per 100,000 residents.

Montana cities that made the 2016 list:

Missoula - #6

Great Falls - #5

Billings - #2

These findings, along with the continued high number of drunk driving fatalities in Montana, are certainly reason for concern. Does Montana party too hard and should additional measures be taken to get drunk drivers off the road? Please comment below.
