I will be moving out to Chicago in a couple of weeks for college and I was wondering if there was any good riding there. I am leaving my DH bike home but will be bring my hardtail. Any good skateparks or dirt jumps. For those of you who live there I am going to Columbia College, about 40 minute train ride from O'hare. It is right near where they built that crazy new park with the amphitheatre. In relation to whatever trails there are, how close am I.
