Not exactly privately owned... but Camrose Hill Farm in Stillwater? They have open catering from what I hear... Other ones are Gibbs Farm, Gale Woods Farm, Reidel Farm Estate, Riley Jacques Barn, Maple Ridge Farm, Little Log House Pioneer Village...
Not sure if you're looking for an outdoor venue for both the ceremony & reception, but most city/county parks have areas you could use. We're having ours this summer at Washington Square park in Stillwater. They have a very pretty gazebo and great spots for pictures.
We are getting married at Cindyrella Garden in Rosemount.....owned by a reverend and his wife Cindy lol. It's super pretty and not too expensive at all.
