i don't know much about minnesota, but i did undergrad at bc, and i just thought i'd throw in a few thoughts about bc.
i'm sure you've seen this already, but according to their career services website, about 10% of their graduates head out to west/southwest (http://www.bc.edu/schools/law/services/career/statistics/
) so i can't imagine there being a huge problem about finding a job in the region (plus, i'm sure their numbers are skewed lower b/c most students prefer to stay in the area). i don't know though, maybe minnesota would be better on that end.
what i can tell you for sure is that quality of life at bc is amazing. have you visited the school? it's not actually in boston, it's in a suburb outside of it. newton is very clean, very quiet, very safe, and is an ideal place for a family, esp. with a young child. plus, the law school campus is separate from the main undergrad campus, so you can live close to the school and not have to deal with the drinking/partying on the weekends (the downside is that if you need anything on the main campus, you have to take a shuttle bus, unless you bring a car). the city itself is like a 10 min. drive (but quite a lot longer by public transportation, maybe 30-40 min, depending on where you decide to live) and obviously, there's tons of culture/history/entertainment/etc. it definitely is a cool place to live, and i think that since you'll be there for at least 3 years, that is an important factor (to me, anyway).
also, i've had only the best experiences when dealing with the schools admin/fin. aid/student services/etc. (although may be different with law school).
sorry i couldn't be more helpful on the law school itself, but let me know if you have any q's about the area.
