This cache was placed during a Cache In Trash Out event, The BIG Picton Cleanup! (Marlborough). There were Girl Guides, Geocachers, Conservation Kids and staff from a host of local business cleaning up Picton. As well as divers cleaning up under the water (they pulled out a lot of tyres!).
It would be great if you could get into the spirit of CITO and pick up a few items of someone else's rubbish today and dispose of them properly. 
The track is a terrain 2 but the cache is just off the track, adding the extra 0.5. Best approach to the cache is to leave the track 30m before the cache - you'll see where. That way you will avoid the gorse.
Supporting the GeoKids program - my caches have treasure, makes them fun for kids to find!
