The coordinates listed above won't help you, they just point to a crossroads. The cache however is within a mile or so of them and is fairly convenient if you're visiting our Rowney Wood Ramble in Debden (Although you will have to drive to it).
The coordinates for the final cache location are obtainable using the following picture. Click on the picture to enlarge it. Assume N51 and E000. There is a fair bit of tree cover at GZ so coordinates are as good as I could get, but I've given a fairly good hint if you're stuck. You can also park at GZ. It's a cache and dash.
The container is packed full of red coloured swag to match the title, however feel free to swap different coloured swag. Original contents:a red car toy, 5 assorted red toy instruments, 2 red dragon keyrings, a red snake, 3 little red ladybirds, a red pirate figure, a small red bag, a red pen (Please do not remove this) and a Thiery Henry (Arsenal!) TB. See this picture for cache contents.
I've rated the puzzle a 4.5 difficulty. I can understand the frustration of puzzle caches, so after the FTF if anyone needs a bit of a hint, drop me an email, tell me how far you've got/what you've tried and I'll gladly give you a nudge in the right direction. Happy puzzling!
