Saw a guy on my local trails today that impressed me. Rocking the full suspension, climbing the big hills, rock gardens, tree gates, etc with a toddler strapped to his back. The little dude was maybe 1 or 2 years old (i'm no expert), had a helmet on, and seemed to be enjoying it. My local trails aren't terrifying by any means, but damn that guy must have some confidence in his riding skills. Or maybe he just couldn't find a babysitter but really really wanted some saddle time.
