A 24-year-old, 65-foot-tall community Christmas tree made the annual trek to Ocean Beach to signal the beginning of the holiday season for locals and visitors.  The star pine, pledged by a local property owner on W. Point Loma Boulevard, made the slow, careful journey through the streets, finally reaching its destination at the foot of Abbott Street and Newport Avenue in the heart of Ocean Beach on Nov. 27.  Local school-children will have an opportunity to decorate the community tree on Nov. 29 from 9 a.m. to noon, and the tree itself will be lit on Saturday, Dec. 1 prior to the 33rd annual Ocean Beach Holiday Parade.
