I decided there was one more space between the A68 and Thornley Village for an additional cache and this one was to be a DISCO.
You can grab this cache from the roadside and there is a spot a few meters away you can pull into though it will block an entrance to a field so only park there to do this cache then drive off, Other more suitable parking is available further down the lane.
I was wondering what I was going to post here for the name - it hit me like a sudden bolt of inspiration - unlike most of my caches its nothing to do with the caches, but the cars whizzed past so fast on the A68!
