In 1973, the Hornsby Heights Cricket Club was formed at this oval, where it ran for three seasons before having to disband due to lack of interest in the sport. But, as you may infer from the vast amount of crickiters you will encounter if you attmept this cache in the summer months, due to a surge in local interest, HDCC reestablished itself at this ground and continues to operate to this day.
So onto the cache. Make sure to bring your own pen. Camoflague is this caches only defense against the hoardes of muggles that roam free around GZ, so please replace it exactly how you found it! On a similiar note, I'd recommend avoiding this cache on weekend mornings, due to the high concentrations of sports muggles that can be found in the area at these times. Early afternoon at around 2-ish is probably the best time to begin your hunt.
Good luck! ;)
Congratulations to Crash and Bella@Waggy for a lightning fast joint FTF!
