The tree lighting ceremony is creeping closer on the calendar. It will be lit the day after Thanksgiving, this year on Nov. 28. The new artificial tree is much “greener” than the trees that have graced the courtyard in years past. In addition to not killing one of the planet’s 120-year-old oxygen generators, as was the case with the trees brought down from North Carolina, the new display didn’t have to be trucked to Florida on a flat-bed truck. The LED lights on this year’s “tannenbaum” consume less than 10 percent of the electricity previously required to spread holiday cheer on the Northbank Riverwalk, further reducing the carbon footprint.
