A lot of very skilled park riders don't freeride at all. Probably couldn't do blues with any skill.
Hmm, I didn't hit the park until the end of my second full season after being able to confidently ride the hardest terrain available at my mountain. I've never understood the people that ride the park all day but never go down a tree run or hike the peak.
Different strokes. My opinion is still be able to ride down some blacks before you start hucking it in the park.
