TwoTykes: I wandered up there today to check this cache. Sad to say that Christmas 2005 is well and truly past!
The container might well be there somewhere but the brambles have rather taken over the whole area.
Apologies to MooreWilsden - please book a "find" at your discretion as you certainly were in the right area by the trampling a couple of yards to the right of the fence corner.
