I ride Busse Woods quite often and it's nice but I agree 100% with jbonus that it can be crowded. Another path to check out is Poplar Creek in the Barrington area. It's a little longer than Busse and hillier (if you can call them hills). It's a lot less crowded however there are several main roads that you have to cross. That's the big downside.
