What defense will Ragged Mountain probably assert?

Alaina Sweeney went to Ragged Mountain Ski Resort in New Hampshire with a friend. Alaina went snow tubing down a snow-tube run designed exclusively for snow tubers. There were no Ragged Mountain employees present in the snow-tube area to instruct Alaina on the proper use of a snow tube. On her fourth run down the trail, Alaina crossed over the center line between snow-tube lanes, collided with another snow tuber, and was injured. Alaina filed a negligence action against Ragged Mountain seeking compensation for the injuries that she sustained. Two years earlier, the New Hampshire state legislature had enacted a statute that prohibited a person who participates in the sport of skiing from suing a ski-area operator for injuries caused by the risks inherent in skiing. Using the information presented in the chapter, answer the above question.
