I thoroughly appreciate everyone's thoughts thus far regarding my decision.
A little more background:
I attended a very large school in a big city (west coast) for undergrad, so I'm not necessarily turned off by the idea of having a similar experience for b-school (or a completely opposite experience for that matter as well). I am also bringing a partner (and a couple of kids) with me to school. We love the Chicagoland area and really enjoyed visiting Kellogg during DAK. We are coming to Hanover for ASM in April, and I think we could certainly fall in love with living in a more remote area as well.
Ultimately, I could see us heading to an office either back west (or south), but both my wife and I are also completely open to living in the northeast as well.
Talking to alumni from both Tuck and Kellogg, it appears that both schools have a good presence at most consulting offices throughout the US (of course Kellogg has a larger footprint given its numbers) so I don't think either school will gate my ability to work at certain office.
I honestly just think it will boil down to which school feels more like "home" for my family. For folks who have picked either Tuck or Kellogg, I'd love to hear your rationale as to why you chose the school you did.
