*548 ORDER AND JUDGMENT **

Plaintiff-appellant Chris Robinette brought this action against Aspen Skiing Company, L.L.C. (“Aspen”) seeking damages for injuries he sustained in a snowboarding accident involving a snowmobile that was operated by an Aspen employee. The district court granted Aspen’s motion for summary judgment because Mr. Robi-nette had entered into an exculpatory agreement with Aspen and had assumed “all risks of skiing/riding.” Mr. Robinette now appeals the district court’s grant of summary judgment, contending that the exculpatory agreement is unenforceable because: (1) it purports to cover reckless conduct; (2) it violates public policy; and (3) its terms are unclear and ambiguous.

Mr. Robinette did not raise a claim of recklessness in the district court; therefore, he cannot do so on appeal absent extraordinary circumstances not present here. McDonald v. Kinder -Morgan, Inc., 287 F.3d 992, 999 (10th Cir. 2002). Furthermore, our review of the record, the parties’ appellate materials, and the relevant legal authority compels us to agree with the decision reached by the district court on Mr. Robinette’s remaining claims. Accordingly, for the reasons articulated by the district court in its order dated April 23, 2009, we AFFIRM.
