Thanks for the comment @intrepidphotos
Ushuaia is very interesting.
They say there can occur all the seasons in one day, weather changes quickly and strong winds are constant.

Unfortunately I haven't sailed, I've gone there hitchhiking. Sailing is definitely is in my plans, I'd love to visit Antarctica.
Do you sail?

If you have the chance one day don't hesitate to visit Patagonia, it's amazing.
