The two landed AANR clubs, Oakwood and Avatan, are just north of the cities about a dozen miles apart.
Non-landed clubs seem to come and go. I've been an on-off member of the Minnesota Naturists over the past few years. I haven't recieved an email from them recently, but they still offer weekly yoga sessions on Sundays in Minneapolis according to their website.
I would say the answer is right here. I am the Founder President and Group Organizer for a brand new naturist club called Northern Bares Group, a nudist social club located here in southern Minnesota. Right now we are actively seeking mostly women but would consider men members as well age 18+ to join. We will be meeting as a group monthly or bi-monthly at a member's home. At the meeting we'll go through the club's agenda, welcome new members all followed by a pot luck dinner party. I'm also planning for future group outings too. Joining is now is completely FREE for the first 20 members with no membership fees for the first year. Hurry because we are accepting new members everyday! Just ask me for the contact information and I will be happy to give it to you.
