Marty’s photo of the day #3176: When Deb and I reminisce about our travels on all seven continents, for my book Cool Creatures, Hot Planet, we inevitably talk about which ones we want to do again. One that I’m reasonably sure we will repeat is our trip to the top of Canada. It was so beautiful (this photo is from somewhere in Alberta), and I still get a warm feeling when I think about the cold nights snuggling into the tent with the dogs—and wolves howling all around us.
