The granddaughter and I had a good swim on our vacation, a 900-metre round trip to a tiny island. The surface water was warm and the deeper water was refreshing.
I mapped our route to get the distance. We figured about 450 metres, and it seems we were right!
Unlike our swim a couple of years ago to the palm-tree island in Nottawasaga Bay, this one was not cold enough for wetsuits. Here’s the map for our 2009 swim in Blue Mountain, which was about 550 m each way and not quite straight.
