Such a shame - for me anyway, but perhaps not for you lot - I'll be there on the Saturday and back in Irelnad on the Sunday. Still, I'm looking forward to being there again after all these years.
I might meet you at stoney on saturday, I fancy staying overnight inside it as I've been meaning to do it for some time.
I'll bring some instruments to test if there are any interesting acoustics inside the chambers.
