On 5/17, sone unknows person(s) defaced the Discovery sign at 69th and Hillcrest . Has anyone else seen grafitti or tagging in our neighborhood. And second, have they reported it to the Glendale P.D.. We can make a difference. Take pictures before it gets painted over, so if the people responsible are apprehended, there can be restitution made to us, the homeowners, for damage to our common property.
