Marty’s photo of the day #3580: Deb and I have renewed our passports in anticipation of reprising our epic trip to the top of Canada this fall. Our original trip, documented in my first book, Cool Creatures, Hot Planet: Exploring the Seven Continents, featured me standing in the midst of a pack of howling wolves and the two of us hiking with the Porcupine caribou migration. While the chances of such magic happening again are slim, something amazing will surely surprise us. I can’t wait!
