Good thinking on the ladder, if I had a second story I would want one too. Also the flashlights. I forgot to mention my defensive guns have weapons mounted lights capable of lighting up the entire yard and I have had shooting with low light/flashlight training in the past.
Cellphones are a given, we keep several charged. Also since we are in a hurricane area we maintain a landline (local area has buried telephone lines) as a backup in case the towers go out. We have lost cell coverage in the past, never the landline.
