Bear Mountain Trailside Museums and Zoo will celebrate the spookiest of seasons with some family-friendly fun during Boo at the Zoo on Saturday, Oct. 30, from 10:30 a.m. to 3 p.m. (Rain date: Oct. 31.) Zookeepers will make spider cookie snacks for the black bears at 10:30 a.m., and then the bears will be let loose on the tasty Halloween decorations at 11 a.m. Throughout the day families can touch real animal skulls, see stuffed specimens in the Nature Study Museum, learn about the not-so-scary owls and vultures, and find out about some of the things that make autumn such a special season. Parking at Bear Mountain State Park is $8. There is no admission fee to Trailside Museums and Zoo, though donations are accepted. For more information call 786-2701.
