Jon Kearley
Park Rep

My name is Jon Kearley and riding my bike is a huge part of my life. All my friends ride bikes and I'm meeting new ones on the trail everyday. I'm also addicted to trail work and trying to make our trails more Sustainable, Safer and Fun. In an effort to be a better rider I am focused on picking safer lines, not fast ones. I never want to stop challenging myself and others. I look forward to see you out on the trails.
