Been reading your blog and enjoying your adventure. Hate to tell you but due to the 1972 Marine Mammal Projection Act you can't bring your seal skin mittens into the USA. They will be confiscated when you go through customs. This has happen before to cruisers and there are plenty of articles on the internet about people being shocked when they are taken away. Any product with seal skin is not allowed.
Do you mean from Tadusacc? i would go on a whale watch. see beluga and other whales and wild life. Get closer to the lighthouse and other scenery. You probably would have some time to walk around the shops near the beach and pier. Plus there is a cemetery and church near by. i liked that part of Canada so much after cruising that the following year we drove up by car and spent a few days there.
