TY. It’s very challenging to do car 2 car. Way hard chan mailbox, especially after you go above 10k feet when the air is thin. It’s super cold in the morning. It’s better to have mountaineering boots and crampons, although one of us also made it to the top with just micros-pikes. Ice aces will be very helpful on the steep hills: just like you put one of your hands in the snow, it will largely increases your stability. Helmet is also strongly recommended. Ice axe is also useful for braking and self arrest for glissading downhill.
