This is the start of some caches in the Three Rivers Vereeniging area. Most will be Evil caches:-) The first lot is placed and will be published to coinside with the Vaal Triangle Event.
The cache is placed next to the Sugerbush River near Vereeniging. There is no need to go to the waterfront or onto the weir nearby. The area is accessible with a normal vehicle if you use common sense. Also pretty safe and is frequented by fisherman. So beware of muggles.
There is also no need to climb all the way to the top of the structure to look for the cache. It is not high up there. There is your hint as well!
You looking for a magnetic nano so please bring your own pen.
