The Ladd Arboretum committee needs volunteers to remove weeds from the Grady Bird Sanctuary in the Arboretum from 1-3 p.m. on Oct. 3. The bird sanctuary is a small retreat for people and animals located about 100 yards northeast of the Ecology Center. The clean-up is an opportunity to fulfill a community service requirement. Volunteers should bring weeding tools. For more information please call Jim La Rochelle at 847-494-1763.
