We're lucky to live in Medina, Ohio - a town with access to over 20 miles of single track through the City Parks department AND the Medina County Park Department. Lately, I've found myself introducing my 10-year-old daughters and their pack of friends to the joys of mountain biking. It started rough - broken bikes, chains, skinned knees and dumb decisions on my part. But, with the help of post-ride Slushees as large as their heads, we soldiered on. Now, we're riding non-stop on trails that used to be problematic. Last week, the girls made their first "stream" crossing.
