Possibly moving to Duluth

I'm from southeast MN, near Rochester, and might be moving up to Duluth. I'm curious about how the social scene is (for a variety of age-groups), and about the reputations of the various colleges/employers locally. For example, down here, Mayo Clinic employees have a reputation for arrogance, which non-locals don't usually encounter. That sort of thing.

I was up to check it out recently, and was very favorably impressed. The town felt much more pleasant than Rochester does, and the morning view of the lake, with the sun slightly overcast but still shining bright...

Anyway, I guess I'm just trying to get a better feel of the town as a whole, and how it would be to live there. I really didn't see all that much.
