In what way - position? And worst as in bad or as in difficult?
Before I had done any work in GCA, I considered approaching Ballybunion offering to restore this bunker: I had an overhead and photos of what it looked like 70 years ago and they explained why Tom Simpson considered it so fearsome / magnificent.
At that stage it was a little, oval pit. I know that it has been rebuilt since but I haven’t seen it in its current form.
