My grandparents had a farm house in western New York State where we visited several different summers. The highlight when I was 11 was swimming in Wiscoy Creek which ran over a little old dam. We had no adult supervision and the town kids swam, splashed, pushed each other over the dam and held each other under water. Some older kids convinced me that a snapping turtle lurked in the deepest water.
Many years later, I took my husband to see this stellar swimming spot. The water fell peacefully over a several inch high dam and my husband said I must have been idealizing the past. Fortunately, this photo arrived a few months ago in a collection sent by my brother. Clearly in the intervening 50 years, silt had filled in the swimming hole, but my recollection was accurate.
As for the snapping turtle..Men fishing in the creek told me that there had never been such a turtle there. The men looked to be my age. Perhaps they were once the boys who had told me about the dangerous turtle!
