Many believe that government needs help but few know that includes volunteers.
Look to areas where you skill sets align with the organization for opportunities. Look for programs that benefit society that have fund raisers which draw the "movers and shakers" of the community. Look for the networking opportunities. The guy hammering nails into the side of a home or the lady cleaning a light fixture could be a corporate officer you are needing to reach. Social causes are gaining corporate attention which frequently results in high profile employees volunteering in high profile social causes. And be professional at all times. You can "pay it forward", get some good exercise, and potentially get connected! Not bad for a few hours of your time!
