I just enrolled in grad school (part-time night classes), and everyone is surprisingly friendly. I have a good group of friends and a MORE than busy schedule now with full-time work and part-time school and a job search and football season and a Cubs playoff race, but I've met some very cool people and a hot new lady friend who seems pretty interested. (Serves me right that the first time in a year I find a prospect, I have no time for women, but I digress)
I just run to the bus stop after class, but everyone in class is really personable and I am already involved in at least one study group in each class (we're encouraged to "cheat" off each other on the homework assignments, too). Just this evening, a girl in my class was at the bus stop at the same time as me, ends up she lives like 3 blocks from me; we were BS'ing the entire ride home, it was cool. {Got her number, too}
I also attended one event (it was a bar night, so I obliged) and again everyone was awesome there. Everyone was very eager to go introduce themselves, talk BS, and just network.
There have to be some events or clubs or whatever, there have to be some out there.
