Chosen answer: The James Bond film "A View To A Kill" came out the year before in 1985. In the film, Bond's snowscooter is blown up by the Soviets, so he takes a wrecked ski from it and improvises it into a snowboard. Snowboards existed at the time, however, it wasn't until that film that their existence became well known. One year later in 1986, they'd still be very rare, but it's likely that his wasn't the first that the ski patrol had seen.
