I live in savoy which is directly south of champaign. however, i don't live in the rural part. I live right @ the edge of champaign. There are a lot of nice areas to live in @ champaign if you just look for them. You just have to get away from the area where the hospitals are at.
However, if you're set on living outside of cu then I would suggest looking into Mahomet b/c their schools are ranked among top in the state.

Plus, it's right outside of cu so your commute time would be very low. CU was ranked 3rd best city in the nation for best average commute time.
The good thing about living out here is that you have the university of illinois (which I attend) so you always have Illini college sports game, famous speakers, plays, performances, various events & concerts. Essentially, uofi & downtown champaign give the area "city-like" things to do while you can still drive less than 15 min & live in a rural area.
This really is a great area. There are, like most other places, parts that aren't so great but they're easy to avoid & no big deal. Where I live in savoy it's VERY nice. There's a bike path right behind my apartments & there are always familys walking together on it. It's very safe & the neighborhoods out here are very nice. Like I said I live in the most northern part of savoy though, not the rural part.
Good luck w/ everything!!! Who knows, maybe I'll run into you @ carle when I'm doing clinicals!
