Boreal, conveniently located on Interstate 80, has become the Tahoe region's first -- and only -- all-mountain terrain park. It has always been a favorite with families and snowboarders, and now it should be a hit with freeriders of any ability. Boreal even has its own Web site dedicated to free-riders (www.JibassicPark.com). Boreal is typically one of the first Northern California mountain resorts to open every season.
