sentences:  When experimenting with successively narrower alpine snowboards to allow for quicker turns, the Fey brothers ended up with a board that could not fit hard-plate snowboard bindings, and tried telemark bindings instead.After a successful trial down a mogul run at Killington (one of the only remaining open trails in New England at the end of that ski season), they continued to refine the design.The Teleboard earned them two patents between 1997 and 1999.
