Hello Top Water,
I do remember exactly what you described! 50 years ago we would take the row boat with a small motor down to Matt Merskis (sp) store, jump off the bridge, and then head over to the little islands and enjoy the candy. I recall my father having pictures from when the island was a peninsula, will need to find those.
I also recall the ongoing erosion of the islands and after one big weather event they got swept away, crazy
