 No, this isn't Sochi or Vancouver. In fact, it isn't even the Winter Olympics. Believe it or not, this insane slope is inside the oldest major league baseball park in the states. You guessed it, these athletes are qualifying to compete in the Polar Tech Big Air Fenway event right here in Boston. This is the really cool scenery. You know, to hit a jump with snow, you've got to take it at the comps and just really enjoy it out here. Skiers and snowboarders traveled from all around the world to come flying down this 140-foot man-made slope at speeds of up to 40 miles per hour for a grand prize of $150,000. Coming from places like Vancouver and Colorado, many of these athletes have only ever gone down real mountains. Yeah, I was actually really scared the first time to hit this. It's so different than being on a mountain. You know, it just makes everything look so much bigger because you're like, wow, the jump I'm hitting is actually the size of a baseball stadium. And a scaffold like this isn't something that can be built overnight. The staging has been three weeks. Watching these athletes come down this slope, I couldn't help but wonder what goes through their head right before they take off. So I was definitely very nervous. I just have to put the nerves aside and focus and be confident in their abilities. Like, I've hit a million jumps in my life, so this one wasn't going to be that much different. Now that Boston is one of the cities that hosts the Big Air event, fans don't have to wait four years for the Winter Olympics to come around anymore. I'm Sanaa Sanjarnia for BUTV News.
