A 10-year-old girl was taken to the hospital after colliding with another person while snowtubing at Nashoba Valley Tubing Park late Wednesday morning, said the park’s general manager, Al Fletcher. The girl collided with the other person at the bottom of the tubing facility and momentarily lost consciousness just after 11 a.m. Fletcher said. She regained consciousness while receiving medical care and was taken to the hospital. No further information on her condition was immediately available. Just after noon, Nashoba Valley had 16 of 18 tubing lanes open.
