We were looking at weather and our relationships with weather. It goes to a few other places, and I don't want to spoil anything, so I won't go into it, but it's about a willingness to expose oneself a little bit more and share something openly and honestly. It's more than just landing tricks. Moving forward, this is just another stepping stone.

It was just on a whole other level, getting to experience and ride that terrain. We spent a fair amount of time in the Hakuba Valley.

When your location is a snowy mountain in the winter the obstacles are pretty extreme.

What you ride and how you choose to ride is such a dynamic part of what this contest [ Ultra Natural] is built for.

Pretty much everywhere we went we had crazy weather. I think Russia was probably one of the toughest places for us weatherwise, but even Alaska, the last three years have been somewhat subpar when you look at historically how Alaska can shape up.

There's no doubt 'normal' is changing - spring actually came a month early in Alaska, for example, and we had to stop filming.

We pretty much had crazy weather, historically speaking, in every location we filmed [The Fourth Phase]. Nothing has been normal in the past three years.
