Walk, run or cycle? Another view of the reservoir. This spot is popular as when the water is low, there is a spit which is great for fishing. I've also seen remote control boat races here in the section between the spit and eucalyptus plantation.
Stealth required here but potentially a very quick grab depending on the number of muggles. Take photos, play with the phone, do your shoe laces (hard to fake in flip flops) and you'll soon have a cache in hand.
*** NB: This is now a nano container like the ones on The Matrix and To The Matrix series. You will need a tool. ***
