The Grossmont Healthcare District’s Dr. William C. Herrick Community Health Care Library, 9001 Wakarusa St. in La Mesa, will host a free senior discussion group presentation on “Emergency Preparedness,” from 10 to 11 a.m. on Wednesday, Aug. 28. The public is invited to attend, and RSVP is not required. For more information, phone the library at (619) 825 5010 or visit www.herricklibrary.org. The speaker will be Tom Amabile, senior emergency services coordinator for the San Diego County Office of Emergency Services. Amabile will discuss the risks and dangers of not preparing for an emergency and how to build your own emergency kit containing items that will help you survive on your own for three-to-five days. Amabile said that two-thirds of San Diego County residents feel that it is either likely or highly likely that they will be affected by a major disaster, but only half have taken the time to formally plan for such an event.
