Spent one year in the dorms, and absolutely loved living in Welch (keep in mind that this was 1991-92). I'm fairly outgoing, but I think even if I wasn't, it would have been an easy floor to meet other peeps. The only downside to how much fun was had was that we probably had one of the lower GPAs on campus as well.
Also, there were also a lot of house parties over at MWL Towers, so we'd hit those on Thursday/Friday nights before heading across Lincoln into someone's backyard to get our drink on.
South Towers was also a hell of a lot of fun, especially on hockey nights.
So, Welch. Welch was great.
