While committed open water swimmers will tolerate the pool, they miss the waves from the open sea.  There were suggestions from the mystery correspondent who sent in this picture (thanks, Glen), that the actions of one M. Watson amounted to disruptive delinquency.  

However, we feel sure that our Marie wouldn’t be into that crack.  She was just trying to make herself feel at home, by creating some wave-like conditions in the pool. Maith an cailín, Marie.
