Soon after entering the trans Canada Hwy 2 from Houlton, Maine, driving towards Fredericton around 8:30 pm on June 10, I noticed that thin layers of fog gradually formed starting from the side of the road over grass. At the higher altitudes, fog was seen getting thicker and thicker in the Saint John Valley. It was spectacular as shown in photos. I stopped several times to shoot photos within about an hour until it was too dark.
