All this month you can go to Fenton's Creamery in Oakland and order the "Firefighter Sundae" and help Oakland Firefighters Random Acts. They in turn help others in need. You get ice cream, they help others...what's not to like?
Also, tomorrow and Sunday there will be firefighters waiting on tables and collecting 'tips' for OFRA. There'll be a sundae building contest, a firetruck for kids to climb on (a nifty old Van Pelt open-cab), and book signings by a couple of authors in the OFD (including Zac Unger, author of Working Fire, a great book on being a firefighter.)
