Sure as heck I break thru halfway across as I luckily was moving forward. That made me fall on my chest and prevented me from disappearing as I was waist deep and never felt the bottom. Managed to pull myself up and made it across breaking thru with my right leg once more. Luckily it was fairly warm and better yet my car key still worked. I've gone thru the ice a couple times and this was real similar.

 

 Wowsers.  I had the same first thought as Queen - you're all alone up there. Glad you were able to pull yourself out.
