There was a cache with a similar name (GC4FPT3) that was located near here. It was owned by Blenheim Bear who shifted to the North Island before I started caching. He eventually adopted all of his caches out to me except this one which was special to him and he wanted to keep it. For a while I maintained it for him, checking after the numerous DNFs, replacing full logs and the like. Eventually it got muggled and BB decided to archive it and said I could use the location to place my own cache if I wanted to. It has been over three months since then and as nobody else has snaffled the spot, I have decided to take him up on the offer. So here it is, in the words of Blenheim Bear himself...
'The BIG roundabout, very slightly odd as there is a railway level crossing running through the middle of it, how strange! But somehow it works, mind you we have 2-3 trains a day in winter so it's not a big thing. Still if you happen to be there at the right time it's worth watching SH1 grinds to a halt to wait for a train to come through.
Very large muggle area, in fact just go for it, so many people from all directions, cars, trains, pedestrians, bikes.. Maybe the invisibility cloak..
Now to the cache, well it's not in the central island (don't want anyone getting hurt), and of course not near the tracks nor in the roadway. But of course it's a round-a-bout the Roundabout, in more ways than one.'
Like the original, it is not in the central island. Also it is not in the same place as the last, so for all of those who found the original, bad luck.
The cache itself has been recycled from a now banned utility box cache, so that should be a hint in itself.
The original cache was very exposed to muggles. In fact I don't believe anyone has got the originol cache without being seen. The problem is the muggles were too busy doing what they were doing to worry about what you were doing. This cache gives you a bit more privacy but stealth will still be required.
You shouldn't need a hint, but you will need a writing impliment.
