In reply to Big Chris:
I know a very good climber indeed who chose a Croatian beach for his honeymoon, "because there wouldn't be any temptation to climb." One day, out swimming, he went around a headland and found a feast of overhanging, tufa-encrusted DWS.
"What did you do?" I asked.
"Turned around and swam back," he replied.
What a romantic!
