Rock Cut Trail Crew Wednesday Ride Night

I recently bought a used 2012 Specialized Enduro Expert EVO but I broke the rear derailleur so I wasn't able to ride it right away until a new one was installed. Here, I'm the one wearing the GoPro (popping noise is chest mount, sorry) and the rider in front has the same bike. Location: Rock Cut State Park, Loves Park, IL Trails: 23 Miles of Single and Dual Track
