Astana is the world's second coldest capital city, with the coldest recorded temperature of any capital (-52, not sure if it was Fahrenheit or Celsius but at that temp does it even matter?)
There is also an ice skating rink at our apartment complex. created from boarding up and flooding a soccer pitch. They recently added benches right outside the gate, and even flooded that area so from the time you get your skates on you are on ice.
Finally, the kids and I went to explore another phenomenon at our apartment - a sledding ramp, all iced over to keep the sled going farther, with stairs cut into the snow mound and a tunnel to play with off to the side within the same snow mound. We played out there for a good hour and the kids wanted to stay longer.
We haven't even looked for the ice city we hear gets constructed around now each year, nor have we yet snowshoe'd or skated on the river. It's a good thing it's a long winter!
