This will be a simple find. Save it for one of those days you just need to find a cache.
Seeing as you won't have to hunt too hard, take a seat at one of the nearby benches and tables and relax. This is a really well maintained but underused suburban park, though you might see the occasional dogwalker. I often walk or jog past, but now I hope to have a reason to stop too.
Another nice suburban park is a short walk away. Doncaster Park is also well kept, and if you happen to visit during olive picking season, don't forget to bring a ladder and a bucket!
