KINGSPORT — Several hundred children in the Kingsport area are counting on the kindness of strangers to have a little something under the tree Christmas morning, and as of Friday it was looking like it might take a last-minute dash to make that happen. “Getting angels returned is probably our most urgent need right now,” Major Joe May of the Kingsport Salvation Army said Friday. The deadline for returning angels in Kingsport is December 19.
