Zombie invasion: What do you do?

I would get a gun, alot of ammo, head to the nearest mall, and wait out the 24 hours for the army to show up, a la shawn of the dead style

Provided that telecommunications are still active, I would check to see how my family and friends are.
And, if still alive, I would make the effort to group with them and formulate an escape plan from there.

This is not only due to love, but due to the fact that nobody has your trust, and your back, more than your family and friends.

Mount a turrent in my room :)

Grab a guitar and go live in the forest.
