Martha Sue Smith, left, rings her family's heirloom bell while talking with Don McCarty during Sunday's 20th annual Louisiana Area Historical Museum Church Walk. Bethel AME, First Christian, First Baptist, Centenary United Methodist, Calvary Episcopal and First Presbyterian hosted activities. Dozens of people heard a Christmas story, choirs, hand bells, a holiday duo and sang carols at the downtown churches. Smith is retiring from her duties as the only tour guide of the event for the last two decades. She used the bell to keep participants moving from parish to parish.
