I apologize for the confusion.
Please refer to the following link.
The Minnesota statutes provide the following definition of notice:
The term "posted notice," when used in reference to the giving of notice in any proceeding or the service of any summons, order, or process in judicial proceedings, means the posting,at the beginning of the prescribed period of notice, of a copy of the notice or document referred to, in a manner likely to attract attention, in each of three of the most public places in the town, city, district, or county to which the subject matter of the notice relates, or in which the thing of which notice is given is to occur or to be performed.
What is consistent is the requirement for placement of the notice in the three most public places of a town.
Please let me know what additional or follow up questions you have.
