Timing is everything in this world and this one is no exception, full few of all around so please use stealth, and do not attempt if people are at the tables nearby.
Lion Park is looked after the local community group that the name suggest, it is accross the river from town so it is not used by as many people but it located on a busy road heading around to the airport and other localities. This park was not as well maintained for many years but underwent a transformation a few years ago. Enjoy the hunt and yes you are looking for a mint tin
