Even the character of the water changed. The color went to a more greenish blue, the surface was rippled, and it felt like we were headed towards the ocean.
Our first view of Sorel, which is at the top of the Richelieu Canal, was of fiery smokestacks. The municipal marina here is nice, and we plan to stay here a day to catch up on laundry, grocery shopping, cleaning, pumpout, and so forth. Then it's boogie for home!
