When we lived in Niagara Falls, we would take our dog with us to watch the ships come through the Welland Canal.
I feel as though I posted this before, at some time.
Anyway .. the guys on the ships would toss us a can of soda or beer, and we would toss them a soda. Sometimes the can would fall into the water, oops!
Moe (our dog) would sometimes get spooked, as the ships were so silent. He'd be lying on the grass minding his own business, then, suddenly this enormous floating "thing" was passing by. This got him up and barking.
