Volunteers are needed in ways that are beyond what traditionally may come to mind.
http://volunteermatch.org/ will connect you with opportunities that match your geographic area, your areas of interest, and your areas of expertise.
After registering and indicating your preferences, every Saturday morning you'll receive an e-mail list of places and organizations that need your help in the coming days and weeks -- many are simply online so you never even need to leave home to participate as a volunteer. I've subscribed to http://volunteermatch.org/ for years and the opportunities never cease to amaze me.
