Class A: Grab the tools from the garage and pull up the stairs, (I always have some boards loose for this emergency). Wait it out upstairs with a tub filled with water and non-perishable foods in my kitchen.
Class B: Take the hidden weapons around my house and load them up along with some non perishable goods and head to the roof with an escape plan in mind.
Class C: Take the hidden weapons around my house and load them up along with some non perishable goods and go from house to house in my neighborhood, taking what I need before driving off in an SUV to a safe location. If the dead are there before I arrive, then I find another one. Once making shelter at the safe place, I only take out a few supplies because no one place is safe, only safer.
If there are any survivors with me during any of these times, it's best to fill them in one what to do and to make sure that any and all wounds caused by anything other than the dead can be treated.
