My event starts in just two days time and the excitement is building.
I've been putting in some last-minute practice and it has been going really well.
I have been riding the Olympic half-pipe at Park City and it was really good. It is the best I have ever been on and all the other athletes were having a good time too.
There is no tension in the air here - everyone seems pretty chilled.

McKenna on her chances
I have been having some physio because I've been feeling quite tired. I think it is because I have been doing so many media interviews!
But it's great that there is so much interest in my sport.
I still haven't decided what my run will be but I will not be doing any totally new tricks.
I do know which music I want played though.
I have decided on Groove Is In the Heart by Dee-lite because it is really cool and will really get the crowd going.
I'm also trying to get a Scottish bag-piper to play - it would make a cool difference from the cow-bells you normally hear!
The opening ceremony is happening on Friday but I'm giving it a miss. I want to have a chilled night instead of the excitement of the ceremony.
Obviously the pressure is on me now.
A lot of people have been tipping me for a medal but I'm not really aiming for one - I'd say I'm in the top 10-15 in the world.
I just want to have a good ride and really enjoy the experience.
But you never know in this sport. We'll just wait and see what happens.
