The Blue Grass course at Old Westbury Country Club occupies a historic estate property in Old Westbury, a village on Long Island's North Shore known for its grand country houses and rolling terrain. William F. Mitchell designed this layout, contributing to the club's multi-course facility. Mitchell, active in the early-to-mid twentieth century, worked primarily in the Northeast and was known for creating courses that worked with existing topography rather than imposing dramatic changes on the land. The routing takes advantage of the natural contours characteristic of this part of Long Island, where glacial deposits left gentle elevation changes and mature tree cover. The property's estate origins mean the course moves through parkland settings with established specimen trees framing fairways and defining playing corridors. The design reflects the period's emphasis on strategic shot values and variety in hole lengths and angles, asking players to navigate doglegs and approach greens from different positions. Old Westbury Country Club maintains a traditional private club atmosphere, serving a membership drawn from the surrounding North Shore communities. The club's facilities support both golf and social activities typical of established Long Island country clubs, where family programming and dining traditions complement the golf experience. The Blue Grass course functions as part of this broader club environment, offering members an alternative routing within the property's overall layout.
