Mad River Glen was one of the first places in the U.S. to allow snowboarding during the 1986-87 season and lasted until the 1992-93 season. Unloading issues due to a flat run-off exiting the old single chair led the owner of the resort to limit them to the Sunnyside Double and the practice area chair. Due to heated debate over this issue, Betsy Pratt, Mad River Glen's previous owner, decided to ban snowboards entirely. Since then, Mad River Glen has been subject to poaching.
