I just stumbled across this and just had to share!
The Three Rivers Park District covers many parks in the twin cities area. On their event page there are TONS of free events, most are geared toward kids and family. I can't wait for my girls to be old enough to do some of this stuff!
You can also search the parks by activities too.
