(Omaha, NE) -- Omaha's official Christmas tree is ready to be decorated at the Durham Museum. The Omaha World-Herald reports a 50-foot blue spruce was donated by a mother in memory of her two young daughters who died in a car accident in 2010. The tree left from the 25-hundred block of South 46th Street around eight o'clock this morning. The tree will be decorated before an official lighting ceremony on the day after Thanksgiving.
