Retired

A phone call from a friend revealed that Dominion was selling ground lamb at $7/lb. Not a bad price.

I grew up on lamb – Western Australian fringe wheat belt – and love it to this day.

I was tempted to rush off and but a couple of pounds, say $20 worth, and make myself some shepherd’s pies.

Then I reflected that for $20 I can buy a boneless shoulder of lamb and pig out for two days on it, roasted.

Also, as we know, chicken and pork are cheaper forms of protein.

So I passed on the lamb, but I am looking forward to spending the money I have saved by not buying the ground lamb, spending it on a shoulder.

Roasted. With mint sauce.

Juice dribbling down my chin ...

Clear Thinking

More flooding, more people swept away. I do not know the circumstances surrounding the disappearance of this Fire Chief, but I do know the circumstances of creeks.

In a nutshell:-

(1) The energy of a moving particle is given by the formula 0.5 multiplied by the mass multiplied by the square of the velocity (Newton). Triple the velocity, nine times the energy.

(2) The energy of a moving fluid is given by the formula 0.5 multiplied by the mass multiplied by the CUBE of the velocity (Puzey). Triple the velocity, TWENTY-SEVEN times the energy.

(3) Pickup trucks have much power; I have seen a an advertisement where a pickup truck tows a large jetliner. Much power! Pickup trucks have no sideways power. When you cross a creek, the fluid comes at you from the side.

(4) If I’ve done the math right, water at twelve inches deep covers an area of the wheels about thirteen times as much as water four inches deep. That’s thirteen times the area for twenty-seven times as much energy to be expended against.

(5) Swollen creeks carry more pebbles (twenty-seven times as much energy, remember) which act like ball-bearings.

(6) These ball-bearing like particles are lubricated

There’s more, but you get the idea.

Never drive across, or walk across, a swollen creek.

Ever.
