On Saturday, April 21, more than 3,000 local Comcast employees and their families and friends volunteered to improve 17 schools throughout California that have been affected by budget cuts as part of Comcast's 11th annual "Comcast Cares Day." At the same time across the country, more than 67,000 Comcast volunteers will participate in this day of service, which has become one of the largest single days of corporate volunteering in the nation since its inception in 2001. Schaefer Elementary in Santa Rosa and Elsa Widenmann Elementary in Vallejo will be part of the effort.Hospitality
