Seeking to promote unity in a time of tragedy, the University of Colorado at Boulder's Undergraduate Academy will sponsor a unity and remembrance walk at noon on Tuesday, Sept. 25, to mark the two-week anniversary of the terrorist attacks on America. The event will convene with a brief program on the steps of Norlin Library on the CU-Boulder quadrangle. Participants will then make a short loop through campus, taking about an hour to complete the walk.
