Cottage Islands in Lake Ontario and St. Lawrence River

We took a trip to Ganonoque, and I am always amazed at the little islands that have cottages on them. Part of it is on the St. Laurence R. and one is a resort. It was a lovely day to get out and do some drive-by shootings! These little spots would be places where people couldn't survive in the good old days. I'm not sure I'd survive on these teeny little islands. These are busy waters!
