Here I am!
And yes, I contacted the owner of the conflicting cache and they have very kindly moved theirs just a little so I have been able to squeeze mine in. A very nice cacher and I'm glad I asked, we had a good long natter about matters local.
Hey - if you fancy checking it out, it's "My Heart Belongs To Hastings" (GC5MRBQ). Come and visit, we have a fantastic town and no end of good caches.
I did have to alter a couple of bits of description but the reviewer eventually listed us.
Straying onto another area this thread has covered, however, is another cache we tried placing at - you guessed it - the bottom of a cliff that we now find conflicts with one on top of the cliff and is almost certainly over 161m away in a straight line! The bugger here is that it's not shown on the caching map because it's the final site of a mystery cache whose origin is just far enough away to be legit.
Hey ho, I can see the points of view on both sides but basically, all we have is phones or GPS devices or laptops with flat screens. Until someone brings out 3D (holographic?) devices I guess I'll just move it on somewhere else...
