We had our second round of "black ice" as well, though no way in heck will you catch me out on it yet! (Only 1 inch) Very unusual to get black ice in snow country. Whacky winter so far...
Much more fun to stay on shore and chuck rocks as high as you can to see if they penetrate, or skip small across the ice which makes some very cool sounds. It is hard to describe. Sounds like... rocks skipping across ice.
