You can carry concealed outside the limits of an incorporated city or town as long as you are involved in a recreational activity,ie: hiking ,biking, hunting, fishing, fornicating, etc. Inside the city limits you should be o.k on your bike as long as it is in the bike. I do recall an instance where Evil Kneivl was cited in Helena in the early 80's for having violated a city ordinance for having a loaded firearm in a vehicle within the city limits of Helena. Concealed carry does state on your person, concealed by an article of clothing. I just would not be smart to be walking around openly packing a firearm around town. Even with a permit you can not carry in any type of bank, government building, or business where alcohol is served as the primary source of business.
