The two ATV riders killed Saturday in separate accidents were each from the North Country, according to New Hampshire Fish and Game.
The first accident occurred on South Hill Road in Colebrook about 1:15 when David Howe, 40, of Colebrook was killed when he rolled his ATV.
The second accident occurred a little more than an hour later on the Dixville Peaks Trail where Clifton Scott, 79, of Stewartstown missed a turn. His ATV also rolled.
So far this year three ATV riders have died in accidents in New Hampshire.
In August a 56-year-old tourist was killed in the southern part of the state near Fremont when the ATV on which she was a passenger hit a tree.
Four people have died in ATV accidents in New Hampshire in roughly the last four years, according to records from New Hampshire Fish and Game.
