Went out for a ride at the Oregon Sand Dunes in Winchester Bay, Oregon.Was having a great time until the accident. My Patella was shattered and my femur was broken. Most of the tendons and ligaments were torn or needed to be reattached and I have no cartilage left in the knee joint. I do have a very expensive piece of metal in there though. Definately goes down as the worst day in my life so far!location: Oregon Sand Dunesoccurrence_date: 08/31/2014[For licensing/usage please contact licensing@viralhog.com]
