Bell ringers Tony Furnivall, left, and Jeremy Bates, demonstrate how to ring the bells at Trinity Church in New York, Tuesday, Jan. 13, 2009. Each of the ropes hanging from the ceiling leads upwards to one of twelve different bells. Barack Obama and his message of change will get a ringing endorsement on Inauguration Day with 12 "change ringing" bells at the church, which is near ground zero. The full peal, which lasts 3 1/2 hours, has been rarely heard in New York City since the bells were installed three years ago. Bates, a Manhattan lawyer and former Obama campaign worker, will be among the 12 skilled ringers who will pull on sturdy ropes in the bell tower to mark the historic occasion.
