Well, Rockefeller Center in New York City has a long history of using trees for their annual holiday display. The first Christmas tree was erected in 1931 and has been a popular attraction ever since. The trees themselves come from various places, but most often they are cut down in the surrounding states such as Pennsylvania and New Jersey. The trees are typically around 75-90 feet tall and weigh around 10,000-12,000 pounds. They are carefully selected and transported to the city in order to create a spectacular display for the holiday season.
