Hi V!
I meant to comment on this when you posted it...
Yes - it IS a bit feckin weird, isn't it? Totally random!
I love it that Historic Scotland do a "free weekend" for Skara Brae - can you imagine EH do that at, say, Stonehenge???
Always nice to hear about Orkney though... Still number 1 on my "Places I Want To Revisit Very Soon Indeed" list!
