My wife's family lives in Portage, and we rode there occaisionally, when we wanted something different than the regular rides at Blue Knob. Nothing really technical, but nice rolling singletrack. Seem to recall getting some 15-20 milers in when we went there. There's a good ice cream place nearby, too...what was the name.....Cole's? maybe??
