I guess in my mind I didn't classify this as in the Urbana-Champiagn area because I'm a broke student so any drive of more than 30 minutes seems like a world away. It's funny because in my review of Nelson I actually call it a "Central Illinois" course, implying that it is closer to Blo-No and Peoria, when in fact you are right. It's definitely an East Central IL course
I agree with your overall comment about the lack of disc golf courses in East Central Illinois. However, have you tried the on at Nelson Park in Decatur? It is built on an old ball golf course and is pretty good.
