Pretty durn cold… But it hasn’t really been cold enough to do this…
When I lived in Minnesota, I used to watch the Ice Races during the Winter Carnival. I miss that… it was fun… cold… but fun.
And after a day of shooting ice races, I would put my closed camera bag in a garbage bag, seal that up and bring it into the kitchen to sit on the floor in a corner. It would freeze up… One time I had almost half an inch of ice on the outside of the bag.
