Your wife sends you out for a leg of pork and some apple sauce.
On the way to purchase the items, you're thinking about how to make your fuel last longest on a long standing patrol on ATAG's 'Bomber Night'.
Hmmm, coarse pitch, zero boost, lean mixture.
It's only when you get out of the car once you've arrived at the petrol station that you realise you don't need fuel, you need pork.
And apple sauce.
True story. Just got back.
