I always thought Coastal Highway is an easier map than Mistery Lake, a ton more shelters and it's also much easier to navigate through it: if you're down the valley or on the ice you can use the main road to guide yourself, if you're up the mountains, you can always go down quickly and you're eventually gonna meet the main road. Mistery Lake instead has less visibility and can be more challenging navigating through it, even if you know the map well: if you're gonna get lost in a blizzard it's gonna happen in Mistery Lake, definitely not in Coastal Highway.
