Craig -- I think Minneapolis (and Minnesota in general) is actually pretty good for schools. The locals might view North or Edison as "problem" schools, but even they are decent performers, at or above the national graduation rates.

Go to Baltimore or Detroit, though, and the urban-suburban disparities are pretty wide. Of course, it's not just educational disparities -- it's demographics, housing, economy, infrastructure, political involvement... it would be very difficult to "reform" schools without much broader reforms in those areas.
