Active volunteer opportunities in San Jose?

I have to do 3 hours of community service for my AVID class and im not really sure where to look. I want to do something active like feed the homeless or clean beaches. I can't do animal shelters because im allergic to cats and i don't want to do anything that involves book work or organizing. I want to have fun while doing it. Maybe run a snack stand or something. Anyone have any fun ideas or they can tell be good places to volunteer. I'm 14 years old.
