My favourite outside pool is 'Parliament hill lido' in London England. It's a unheated 60m stainless steel lining pool. Frequented often by English channel swimmers to train in as it's unheated and long at 60m. At night the pool wall perimeter lights reflect below upon the stainless steel lined pool like deep sea light emitting fish. So surreal. . . My favourite pool:-)
We began swim lessons at the end of January. In the beginning, my son didn't want to have anything to do with going in the water. In just a matter of two months, he is now swimming underwater by himself several yards!
