Just to say that you have nothing to worry about with your cache but below is a quick summary so that you can have some feedback
The coords were well within the limitations of my GPS in my view excellent.
The 1 star for terrain I think is correct although the first wheelchair user to the cache may like to confirm that.
The contents of the cache were excellent far better than most caches I have been to.
The 1.5 star difficulty is probably correct, the cache is well hidden, if a couple of cachers struggle then you could bump it up to 2, but 1.5 is good as a start.
This is being picky so you may want to ignore it.
The only problem you may get is in the autumn it may become visible from one of the footpaths and attract unwanted attention ( As I left the site I could just about make it out through the leaves once I knew exactly where it was). if it it does start to become visible a plastic bag will probably make it look unimportant and not worth the trip to investigate
The main thing is this was a very good first cache and I look forward to doing others of yours, especially if you put out some harder ones (I am a difficulty star tart)
PS couldn't find the €20 note
