Aye, its always good to meet someone with the same daft obsession - my family think I'm a tinny short of a sixpack!!!!!.........but at least we all like Shin Falls - magical place about Christmas time.
I know a couple of other "stoneheads" in our area, but unfortunately they dont post on here.
Talking of obsession, it must be great to be able to combine yours in the form that you do. I take away something different every time I visit/revisit a site. Unfortunately I'm not artistic enough to express that in any kind of unique way. In short, I have all the creativity of a brick!!
