Leelanau County Road 667 is a roller coaster from M72 to M22. There is a section that deserves special notice between Kasson Center road and Maple City; there are three small hills right in a row that are a blast to hammer over. If you have a strong wind from the south you might even find yourself doing laps on this section; yes, itís that fun. Just loop back around on Valley, Newman and Kasson Center roads.
