Bring the kids to the S.B. Zoo (500 Niños Dr.) this weekend for Boo at the Zoo, a safe and fun child-friendly Halloween event. Kids will be delighted while trick-or-treating in a “merry-not-too-scary” fall setting as the Zoo transforms its animal campus into a safe, traffic-free zone. The event runs 5:30-8:30 p.m. from Friday-Sunday, October 22-24, and costs $9-$12. Call 962-5339 for more info.
