Kerfuffles: I went out to have a look at this cache yesterday. After much marching up and down the road, peering and marking waypoints and measuring I came to the conclusion that there was nowhere I could move the cache to that wouldn't take it too close to adjacent caches (to be fair the area of possibility was very small [:(] ).
On this basis I've retrieved the container and taken the decision to archive. A shame - thanks to all the 607 cachers who've visited over the past 3 years or so.
