This geocache is not at the published co-ordinates.
I was up in the area bagging puzzle caches and drove passed this spot. I pulled over just to check if someone may have popped a cache here. I couldn't spot one. So here goes.
There is parking close to GZ.
Work out the co-ordinates for the final using the images below. I hope you find the cache 1st Class. Stick at it, you'll soon have it licked.
edit: 30th July, I've amended some images to tidy things up and one was causing an issue
