The Corvette had some extra dust on it, just checked. For some reason, there's a TV crew van monitoring my next door neighbours in my access road. Saturday night on ITV, they said.
Anyhow, I woke up, my unconscious mind had registered what was going on because I sat bolt upright. Then the noises stopped about a second later, leaving me sat up wondering why I was awake. Then I lay down and fell asleep.
I now know what my sleep/awake threshold is: 5.3 on the Richter scale at ~120 mile range. No wonder my alarm clock has a tough time of it.
