Here's a look at the Strait of Magellan in the evening, as the sun prepared to sink behind the islands of Tierra del Fuego. I had walked -- briefly -- along the beach that afternoon, but it was too windy to be enjoyable.
And when I say it was windy in Punta Arenas, I mean the sort of wind that accompanies a really bad nor'easter or mild hurricane in New York, or a sail through the Lemaire Channel in Antarctica, not wind so much as a full body punch that can literally knock you over if you're not careful. I read somewhere that in the winter there are ropes along the city streets so people have something to hold on to against the winds.
I can testify that they'd be useful in the summer as well.
