I'm from Rochester, but my brother went to school there (Oswego State College) and I've been there a few times. Unfortuneatly, I was in college at the time too, and can't recall too much! Too much partying while visiting my brother!}(
If I remember right, there isn't too much, but an area for some good long runs or bike trails if you like that! They might have some boat rides on the lake(ie: sunset cruises or see the area ones) those are usually pretty neat.
I agree with the others, check out Syracuse, closer than Rochester. Hopefully, you'll be there for the NY State Fair. That's fun. They usually will have some good concerts too, I'm not sure who is coming this year though.
Enjoy the peacefullness!!
