If you were up and outdoors under clear skies before dawn this morning, then you witnessed a beautiful full moon. And if you're still up tonight celebrating the end of the decade, you'll see yet another full moon, much like the one on Dec. 2, which makes tonight's occurrence what we informally call a blue moon (though it isn't blue).
It's a phenomenon that hasn't happened in about 20 years, and I think it bodes well for all of us, don't you? Cheers!
