I chew where smoking is prohibited and when it gets too far below zero. I can dress for the cold so I've been known even at -10 to hunker down beside my camera and stuff a bowl. It's all about what you grew up in and can tolerate I suppose. Wolf skins make for toasty hats, pants, boots, parkas and gloves. Nothing like real fur, thick, to combat the real cold. Even though smoking reduces body warmth. wolf, wolverine and such trap what there is and keep one comfortable. Gotta dress for the weather! That "man-made" so called "cold weather gear" just won't cut if you must spend time in the cold.
