There was the river with its uniquely shaped swimming holes spaced distances apart, linked by an all sorts jumble of rocks splashed upon mercilessly by the frantic stream of water eager to reach the sea . Avyoung child would start swimming at the lower pools and graduate up the river as they grew older. Soon able to go without adults one would braved the swimming hole aptly named "beer bottle" which was a bit of a walk in the intense summer sun beyond the locked gate. If you arrived past noon the sandy beach could be covered with people sunning their bodies on various rectangles of blankets and towels. On your first attempt to enter the slow moving water your breath wold be taken away with the icy shock but became much less traumatic with each successive dip. The water dripped in beads off your baby oil smeared skin that was either sun fried red or tanned at the end of the day, depending on your heritage. The burned ones always clung onto "maybe this time I will tan", but WOULD learn eventually that it was never meant to be. (ask me how I know)
Unfortunately sunblock had not been invented yet.
