RUNNING with its customary full quota of entries, and a waiting list of disappointed riders, Grove celebrated its 25th anniversary of affiliated eventing last weekend. The Ponsonby family’s venue has enjoyed a long association with all things equestrian, which began when William Barton introduced a pack of foxhounds to the estate in 1820. In the years that followed, the park has provided an idyllic venue for Pony Club meets, rallies, and gymkhanas.
