You and a group of friends are hiking a beautiful trail in a national park during winter when all of a sudden a freak snowstorm hits. Luckily, you find a warming cabin, a shelter put specifically along the trail for anyone who might be stranded. Inside there are blankets and general supplies, but the food put there by the park rangers is all locked up so animals can’t get to it. The codes are hidden somewhere in the cabin. You don’t know how long you’re going to be here, but as the snow begins to quickly pile up, it’s better to be safe than sorry.
