i have a Wyoming Concealed Permit.
I'm not reading in the part where it says you can carry open in a bank, school etc. Maybe you can direct me to that one.
Laws in the United States do not define what is a legal activity. Laws in the United States define what is illegal activity. So, the question is not, "Show me a law that says it is legal." The question, in the United States' legal system is, "Show me the law which makes it illegal."
The website you have posted:

contains correct information. Notice, "No weapons, concealed or otherwise, are allowed in school buildings in Montana." is correct because of this Montana law:
"45-8-361. Possession or allowing possession of weapon in school building -- exceptions -- penalties -- seizure and forfeiture or return authorized -- definitions. (1) A person commits the offense of possession of a weapon in a school building if the person purposely and knowingly possesses, carries, or stores a weapon in a school building."
So, let me ask you, show me where Montana statute 45-8-361 allows me to carry books into a school building? Where is the law that says books are permitted in the school building? Of course books are permitted in the school building; why? Because there is no law that prohibits books in school buildings.
Notice this from the website you posted, "Even with a concealed weapons permit, you may not carry a
concealed weapon in the following places:
buildings owned or leased by the federal, state or local government
financial institutions
any place where alcoholic beverages are sold, dispensed and consumed" which is also a true statement based on this Montana statute:
45-8-328. Carrying concealed weapon in prohibited place -- penalty. (1) A person commits the offense of carrying a concealed weapon in a prohibited place if the person purposely or knowingly carries a concealed weapon in:
(a) portions of a building used for state or local government offices and related areas in the building that have been restricted;
(b) a bank, credit union, savings and loan institution, or similar institution during the institution's normal business hours.
(c) a room in which alcoholic beverages are sold, dispensed, and consumed under a license issued under Title 16 for the sale of alcoholic beverages for consumption on the premises.
There is NO law in Montana that makes it illegal for you to open carry a firearm with or without a license. There is NO law in Montana that makes it illegal to openly carry a firearm into a bank, government building, or place serving alcohol. So, my question to you becomes, "Show me the Montana statute that makes open carry illegal in a bank, government building or place serving alcohol." There isn't one. Therefore that activity is legal, just like carrying a book into those places would be legal, because there is no law against it.
