The lighting ceremony will be Saturday, December 1st at 6:30pm at the Civic Plaza with students caroling and hot beverages. This year in addition to the tree lighting ceremony our partner, Collaborate to Impact, and several local restaurants are organizing multi-site happy holiday hours to raise funds for three nonprofits serving our area. Tickets for the happy hours can be purchased ahead of time for $20 at participating restaurants, Latin American Youth Center or at CTI’s website. You can also purchase tickets at the ceremony for $25. For more information people can check out facebook.com/chtreelighting or email us at chtreelighting@gmail.com.
