DAHLONEGA — Members of the Childs family know where they’ll be during today’s solar eclipse — home in Jefferson. And they’ll be actively watching the skies, Dan Childs said as he helped his children build a solar eclipse viewer out of cereal boxes Sunday at the University of North Georgia’s solar eclipse program. “This is a once-in-a-lifetime thing,” Childs said. “I’ve seen it and (the children) have seen it on TV, so we can (watch it together) and know what’s happening.”
