I got incredibly lucky and the disc ended up upside down and in bounds:

Grateful! Indeed, playing in the freezing cold of Colorado is very difficult to play to its full potential given the slippery icy surface as seen in the photography you shared.

However, it is good to know that luck is still on your side.

And it's also nice to know that you enjoyed today's game even among the cold, frozen ice.

Enjoy your day there!
