Winter time

In my city winter has come because of snow falls. I hope it will be a snowy winter.
Winter is a lovely time because we can go skiing or snowboarding. In last two winters I snowboarded. It is the most difficult exercise that I've ever met before. I remember when I tried to go down from the hill I was scary for the first time.
After a few downhill I could do it. But I still fell down to the knees or back, and it was painful. I think I need to change from snowboarding to skiing.
