I was in New York in February, where it was unseasonably warm. So warm that you could see stuff like this in Prospect Park:
Yesterday I was out walking around the lake Damhussøen in my native Copenhagen. Here it is unseasonably cold for March (although not in the what-the-fuck-it’s-68°f-in-New-York-in-February category), and the lake is completely frozen:
But in Denmark, you’re on your own. To be fair, based on tracks we saw, it seems that people could actually walk on Damhussøen, though I doubt it’s something anyone would recommend.
