WMUR is doing a good job of keeping up with the story.
What is known so far: accident involved ten bikers, heading eastbound, 500 feet from where they were staying. The bikers were part of the Marine Jarhead Motorcycle Club, having a reunion in Randolph. The truck was an auto mover from Massachusetts, heading westbound. Investigation is still underway, but it appears to be distracted driving on the truck's part, possibly speeding as well. It was along a stretch of straight road, so no turns were involved. Seven bikers dead. Two treated locally and released. One was med-evaced to Maine and is critical condition.
