My husband, son, and I went walking in part of the Tinley Creek Trail System of the Forest Preserve District of Cook County. We walked a portion of the Green Trail Spur which connects two much larger segments of this large preserved area of Cook County. The paved path is mixed prairie and woods, but part of it is adjacent to a residential area and another part runs right along Oak Park Avenue. It’s a unique part of the trail system. Although it’s not particularly large or beautiful, it connects miles and miles of trails for biking, running, and walking.
