A few other things:
26. When placing everything in your garage make sure your bicycles and wagon are accesible, otherwise you'll have to redo the whole thing.
27. We had plenty of food, water, batteries, duct tape, tarps, and diapers, but I forgot to buy more kitty litter.
28. Make sure your back-up power source works! Several years ago I had picked up a deep-cycle battery, a automated charger, and a 400-watt power inverter. This system was capable of running a small tv and several fans for many hours. I just left the charger attached to the battery for the last four(!)years. When I pulled it out Thursday to make sure it worked I discovered that the battery had gone bad and it was too late to get a new one. D'oh!
