That warehouse is the base of operations for Santa’s Posse, a huge volunteer effort that’s driven by the Clark County Sheriff’s Office and a whole bevy of other partners. The point is to bring Christmas joy — meaning gifts, food baskets and personal care items — to families who can’t afford any.Organizer and sheriff’s Sgt. Kevin Allias took a break from helping out on Tuesday to say that the whole thing got started nearly two decades ago when patrol officers started noticing extreme need during their normal rounds.
