The Anchor Replacement Initiative (ARI) is made possible by volunteer equippers such as Micah Gentry. During the spring of 2011, Micah updated six routes at Castle Rock, Tennessee, with new hardware provided by the ARI. Updated routes include: Slingblade, Chestnutt Route, Entrance Corridor, Right of Scarlet, Scarlet Begonias, and Unfinished Business. See more ARI updates here.
