I live in the Midway neighborhood in Saint Paul, Minnesota. There is a very orthodox parish about 10 minutes from my house that has a Latin mass every Sunday and weekdays too I believe - Saint Agnes. http://www.stagnes.net/index.html
I go to the Cathedral of St. Paul for Mass because my rest of my family attends there, and they have a pretty active community and lots of cool things that go on throughout the year: the Parish Festival, Saint Patrick's Pancake breakfast, Young Adults group Valentine's Day dance, Moms group All Saints Day party,etc...plus there are various groups for families and individuals. I also always see tons of moms/dad with their kids every Sunday.
Not 100% sure about homeschoolers in the area, but I found this helpful website that lists some homeschool groups in MN http://www.home-school.com/groups/MN.html
Also...There are TONS of farmers markets in the city, and there is an International Market fairly close to the Midway neighborhood that has not only veggies and fruits, but all sorts of things: clothes, shoes, food vendors of all kinds, etc. It's pretty awesome.
