Colorado ? A 60-year-old man is taking an 8-year-old boy and his dad to court, claiming the boy caused a ski-slope collision that left the older man with a shoulder injury.

David J. Pfahler of Allentown, Pa., sued in federal court in Denver, claiming Scott Swimm, then 7, was skiing fast and recklessly when they collided in January, the Vail Daily reported Thursday.

The suit claims Pfahler suffered a torn shoulder tendon and seeks compensation for physical therapy, vacation time, nursing and medical services provided by Pfahler’s wife, and other expenses. It estimates the couple’s losses at more than $75,000.

Scott’s father, Robb Swimm, said that he saw the crash and that Scott was skiing slowly and in control.

“It wasn’t a violent collision or anything; Scott just kind of tapped his ski boots,” he said this week.
