Yuletide madness began Saturday as the legendary Rockefeller Center Christmas tree has officially rolled into town. Tree donors Shirley Figueroa and Lissette Gutierrez accompanied their 72-foot-tall Norway Spruce from upstate Wallkill as made its way to Midtown on a massive flatbed truck, ready to settle into its new digs. “We’re honored, we’re happy, we’re sad to see her leave a little bit but we know that everybody is going to enjoy it,” Gutierrez said. Figueroa said she was stunned when her tree was chosen for the iconic spot. “They came knocking at my door and I was like, ‘Is this a joke?’ I didn’t believe it,” she said. “It’s amazing. I know this is like the most New York thing to do.” The tree, nicknamed Shelby by the couple, weighs in at an estimated 12 tons and boasts a 45-foot diameter. It will get decked out with more than 50,000 multi-colored LED lights and be topped by a new, crystal-encrusted Swarovski star designed by architect Daniel Libeskind. The music-filled lighting ceremony will kick off on Nov. 28 at 7 p.m. The tree will stay up until Jan. 7.
