The birth of Jesus Christ will be the centerpiece of activities this weekend during a three-day Festival of Nativities.An estimated 350 nativity sets are scheduled to be on hand to complement live music, poinsettias, and Christmas cheer this Friday, Saturday and Sunday.“Some people say this has become part of their Christmas tradition,” said Miriam Crawford, one of the organizers. “They bring their kids and their grandkids and have a wonderful time. This is a community event intended to remind ourselves and others of the reason for the Christmas season.”Festival of Nativities, set for its fourth year, has a new location off the bypass at 562 Shangri La Lane at The Church of Jesus Christ of Latter Day Saints Assembly Hall.
