For those who like to be out for a stroll/hike and quantity hunt.
Remember to take down those hints for the bonus cache at specific waypoints.
Be care on the handling of the cache as there is H2O risk; if required, you may bring along extra "magnetic pouch" cache container and assist to replace if muggled.
WP Hint : go to the nearest black lamp post, check what is the number on it - 3 similar digits. Added them together and this is nuumber "A" for the bonus cache.
Enjoy & have fun !
