Craig Hammerman wrote in with a suggestion for those looking for local volunteer activities:

Assemblyman Brennan’s Office revised the Volunteer Directory for the
2008 Volunteer Fair we put together a few month’s ago.  I think you’ll
find it a great resource for anyone looking for a volunteer
opportunity.  The full document is posted on our website and is
downloadable by clicking here, or using the following link:

I hope you find it helpful.  Please do share it!
