From the hares, “The On Out is from the bus stop at corner of Horsham Road and Pitland Street in Holmbury St. Mary. Park on either side of Horsham Road or left hand side of Pitland Street. Do not park at the On Inn.“

On Inn is nearby (walking distance) King’s Head (~RH5 6NP). The kitchen closes at 9 pm, so pre-order any food.
