Temp about 13C when I left home. Slight headwind. There was fog on the St Lawrence river, so I couldnt see if the bridge was raised for a ship at the St Lambert locks. If I see it raised I divert to the Jacques Cartier bridge - which is the same ride distance but involves a 130' climb. Fortunately there was no shipping going through the locks. When I got to St Hubert airport the fog was so thick I had to stop and put on my blinkies. My glasses also fogged.
