Darien Lake Amusement Park's 2015 season opens tomorrow at 10:30 a.m. and a thrilling new seven-storey circular ride called "Rolling Thunder" will be there to greet you. Darien Lake's newest 70 foot tall attraction made its public debut this morning at a special ribbon-cutting ceremony. Local dignitaries and Darien Lake officials were on hand to open the ride. The moment the ribbon was cut, the crowd swarmed the turnstiles to be the first in line to experience "Rolling Thunder." The other new ride making its debut in 2015 is "Brain Drain," which will open next weekend.
