I happened upon your post today almost by accident. It's been a long time since you left your message so I assume you have since "found" minnesota junction. My great grandparents owned a farm at the end of East Street in Minnesota Junction when I was young. I visited often as a child and have many fond memories. Incase you haven't found it it yet it's basically at the intersection of Hwy 26 and Hwy 33 in Dodge county. East Street enters off 33 and I believe North Street enters off 26. Hope you found all you were looking for!
