Spokejunkies : “The Spokejunkies are a group of fun-loving yet serious recreational [mountain bike] riders. Members range in age from 16 (the group-imposed minimum unless accompanied by a riding parent) to, well, let’s just say they’re old enough that they’d rather we not say. From blue collar shift workers to PhD-toting psychologists, the Spokejunkies appeal to all with one common factor, the quest for a great ride and a good time. They offer the beginner a forum to ride in a large group while learning valuable information from more experienced riders. The site includes reviews of Ohio mountain bike trails as well as a few trails from some other states.”
