It's never free, besides when they opened up after that one freak storm last year just for fun. Then they shut down again for like 2 weeks. Last year was the first time that's ever happened, so I doubt it's free this year for the official opening.
Open top to bottom, nice layer of pow everywhere, couple little tiny jumps in the park, some crazy new urban stairway thing and some very odd boxes I wasn't sure about. Pretty much the most insane opening day ever. And it wasn't even crowded which blew my mind.
