13-3. Disafrmance. J.T., a minor, is a motocross competitor. At Monster Mountain MX Park, he signed a waiver of liability to \"hold harmless the park for any loss due to negligence.\" Riding around the Monster Mountain track, J.T. rode over a blind jump, became airborne, and crashed into a tractor that he had not seen until he was in the air. To recover for his injuries, J.T. led a suit against Monster Mountain, alleging negligence for its failure to remove the tractor from the track. Does the liability waiver bar this claim? Explain. [J.T. 1/. Monster Mountain, LLC, 754 F.Supp.2d 1323 (M.D.Ala. 2010)] (See Contractual Capacity.)
