When I was kid, we often spent many weeks at the cottage. I would bring an enormous stack of books, Oreos and sunglasses down to the lake and spend the entire day there. Often, the black flies were out of control and the only way to get away from them was to go underwater. Other times, when the heat was the major problem, I figured out a wonderful way to float the days away. Lifejacket to use as my own lounger. Flippers in case I ran aground and had to paddle back out. You'll notice I was in the middle of my John Grisham phase with 'A Time To Kill'. Only a handful of books returned to the library water-wrinkled. A blissful way to spend a summer day.
