We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember Steve Walker
saying something like:

Didn't the Germans used to put petrol in the engine oil of their
Messerschmitts during the cold Russian winter? The petrol would thin the
oil so they could start the engines and then as they warmed up, the petrol
would boil off.

The tanks, too.
