Wasaga Beach, about 30 meter wide stretch of sand, 14 km long. Here photographed near 39th street, but the view is almost identical at 29th street or 16th street.
The only reason I know, it is 39th Street is that I had to remember where I parked my car!
The sign says, dogs are prohibited on the beach, which I find sensible, no matter how big is the beach, because not all dog owners are responsible! (I know, I know, neither are people....)
