What's the event?

From an archive of Morrison photos, we are trying to ascertain what, when and where in Moycullen this event took place.  It looks like a horse race, possibly at Homefarm on lands owned by Johnston Morrison (previously Lord Campbell’s lands) and maybe in the 1930s?
We would be grateful for information anyone may be able to provide.  You can leave your comment at the bottom of this page or alternatively email moycullenheritage@gmail.com or phone 087 4364699
