Tyler Van Note, 10 (top) and Sean Reimers (right), 9, both of Walnut Creek, use an atlatl to hurl a spear at a "mammoth" target while participating at the Ancient Ways gathering at the Sugarloaf Open Space on Aug. 10. An atlatl is an ancient throwing device, usually consisting of a stick fitted with a socket to stabilize a spear or dart -- typically used in hunting -- to help the projectile travel farther.
