I’m making a snow cave. We use to make igloos as kids. We’d form each brick but that would clearly take too much time here. But they were warm. We could go without our coats when we were in the igloos as kids. 😊
I started thinking about my choice after I posted last time and wondered if it would make you turn into a snowball! Ha! Then looked it up. Swimming toward the top is the best option. Or trashing to stay at the top. Which, I think your survival instinct would kick in and you would naturally trash around grasping to stay on top of it.
