No weapons? Well... I do have a few knives, although I don't have any firearms at my house. I guess I'd pop out my window and crawl on top of my roof. Wait till the all clear then go from the tree to the car, drive recklessly until I see someone friendly or a lack of people. Then I'd stock up on essentials. Drive to some defendable location and fire at anyone in range.
Assuming I don't get eviscerated before I leave the house.
