I agree to meet Noden to exchange survival strategies and after hearing the explosions try to suggest to Valeranos that bombing the Walkers won't help much. He could damage a section of our building creating another entry point for the walkers, plus explosives are a lot less likely to take them out and might even create little zombie head land minds. Explosive largely depend on shrapnel to do most of the killing, and it would require a lot of luck for a pice of shrapnel to kill more than a couple of zombies. Plus the sound will draw even more in our direction.
The explosives can be handy for creating emergency exits in a pinch or getting into sealed buildings for supplies when necessary. But for now just keep them handy.
We should also have a plan to dispose of corpse, weather Walkers we put down our living who die for other reasons. Decaying flesh can spread infections that can be as fatal as a walker biting us.
