Unfortunatly all we have is a car parked out front surrounded by the dead...I dont have the keys, i lost them in the initial outbreak....i would be able to hotwire it but it might be a little dificult with all the reanimated flesh eating corpses standing next to me....theres about 40-60 of em outside at a time.....we would go out there with blunt objects but theres a problem.....there undead are a mix of conventional, slow moving zombies, and the Romero style infected runners....
If you own a truck that's in a attached garage, have the passenger throw open the garage door, jump into the cab of the truck and then you back out at high speeds. Use 4 wheel drive if you have it. Drive backward, demolition derby style, and back over the undead. Hitting them with the front of the truck could lead to engine damage. No fun being mobbed by zombies. If you can't escape, save a bullet for you, and one for your partner.
Decoy. They have very sensitive hearing and they are both stupid and ravenous. One of you has to appear to be vulnerable (but not really) and attact them to a place opposite to where a person needs to exit. There also needs to be a signal for when this person returns so the decoy can attact them away from where the person must enter.
Don't let your self become trapped. Letting yourself to fall victim to the thought that your home is a fortress WILL get you killed.
If there are ten outside your house it is most likely time to go. At this point it should become obvious that the authorities are unable to stop the spread. At this point waiting for help will most likely lead to a desperate situation like what you described. Don't let yourself get cornered like this. If there are 60 of them outside your house there is a very good chance that thousands wait beyond them.
