With classmates watching, Knowlton Elementary fourth-grader Lauren Anderton tries tomahawk throwing after a lesson Friday from Mountain Man Rod Larkin. Some 200 Utah fourth-graders, with teachers and administrators, on Friday visited the The Labor Day Weekend rendezvous at Fort Bueneventura State Park in Ogden. It was the 10th anniversary celebration of the gathering. The event, which ran through Monday, features primitive camps, muzzle-loader competition and a variety of traders catering to visitors and participants.
