Unidentified Aerial Phenomenon. The Sims UAP Snowboard is today’s version of the Shaun Palmer UFO model of old, a classic from a polarizing rider who pushed as many boundaries as he did buttons. It’s a long-nosed twin made for freestyling, hot dogging, and all around snow-based hooliganism. Stiff and traditionally-cambered, it’s all about that pop, and the throwback shape will have you hunting for silver tuxedos and hair dye.
