Well, here's my official plan:
1) Phone/text/email my friend and see if he's alive/if it's safe where he lives/if it'd be possible to drive over without getting eaten (his house is much more zombie-proof than mine).
a) Assuming the criteria are met, I go over, help him barricade the place, and then travel using the rooftops of the nearby houses to get supplies and such. Then we'd signal for help to the National Guard dudes that inevitably come.
b) If my friend is dead/whatever, I'd find the nearest easily-barricaded commercial building, clear out any zombies inside, team up with any still-sane survivors, barricade the place, and carry out the plan as usual.
Of course, this doesn't take into account things like the government pulling a Half-Life (sending in army dudes to silence all survivors).
