In the nineties, MCA (Adam Yaunch) would spend a great deal of time snowboarding at Utah's Snowbird Retreat. For a time, he rented an apartment with pro snowboarder Mike Basich. At other times, he would have a barren apartment meant for suiting up, showering, and storing a beat-up Subaru to get to the slope lifts. Some sources state that he would use LSD as eye-droplets during this period, using them on lifts and then hitting black diamond slopes.
Writer Melissa Larsen remembers meeting MCA on the slopes in an ESPN article- here.
