I'd take my baseball bat and try to see if I can smash some. Then I would brag and gather people around me by my tales how many zombies I've killed.
This would work fine unless I will have met a leader who seems to "know it all" and takes over responsability and my group of followers, and who leads us all to our deaths! Then he will show explanations why our fight was in vain, and I'll smash his head with my baseball bat before succumbing to the zombie hordes just to make sure he understands.
Oh by the way google for "rebuild" zombie game. Turn-based tactical survival, it is teeeeh top browser game these days! You gotta play this one, it has got 1 million plays in the first week alone and the top flash game of all times has only like 9 million plays combined over 5+ years. So you better reserve a chest of beer before tackling this one!
