Can I walk around town with an open beer can?

In Bozeman, and most cities in Montana, it is illegal to possess any open container of alcohol in any public place, even if the container is empty. A red cup is a red flag; so don’t carry your drink with you in public. An open container citation in Bozeman can come with a fine of up to $500 and possible jail time. If you are under 21, it may also result in an MIP.
