Great after-action report.
Again, never heard the sandbag thing. Filing that away...
I love how you clarified the consumables as "milk, bread" I bet you bought eggs too, right? AKA, the infamous disaster "French Toast Diet."
I'm rather suprised at how many times you went out in the car. Looking back on it, would have done the same, or would you have just hunkered down? It seems you had several close calls -how prepared were you to be cut off from your house with all its lovely supplies?
Glad your wife had her light bulb switched on. the trick now is to keep her from bragging to the entire world, lest you have a crowd of folks show up at your door some day. Prepping for yourself and maybe some friends, sure. Prepping for the entire neighborhood and half of Brisbane? Not so possible.
Glad you're safe.
