The students of PBAGS (Plant Biology Association of Graduate Students) have put together a great resource for those living in CU or considering moving here. Life in Champaign-Urbana serves as an introduction to the community. It covers a general overview, organized activities, food options and how to locate a good place to live. The section on housing is particularly helpful.
If you are new to the area, go take a look. Hopefully it will be helpful. If you are a CU-pro, take a look anyway. Maybe you can leave some suggestions below on how the resource can be improved?!?
