Oymyakon, Russia, has a substantial, ongoing population of 4,000, and its temperatures have fallen as low as 72 °F ( 58 °C).
People have visited spots even colder, though. In Vostok, Antarctica, people were present when temperatures got down to 89 °F ( 67 °C).
But no one has set up residence there yet.
Too bad, we suspect the real estate prices would be quite reasonable.
