Last winter I went to Sapporo during the Snow Festival and spent a day at Sapporo Kokusai resort. It was -9 brr! It was probably because of the snow festival that it was really crowded there, and the runs all ended at the same place. \r\n\r\nBut everyone, from little kids to old people, was really experienced there, and they zoomed down the runs.
Personally I didn't have a good day and Kokusai kicked my ass!
