Actually now that I think about it I have a much better story to tell.
When I was about 19, I used to deliver and take down Real Estate signs like these.
Basically, real estate companies need to put houses on and and off the market every day. So I was the guy that would take the morning list of 50 homes, and go around, putting up sign "for sale" here, taken down another sign there etc. Actually the short version of this was "I used to do deliveries".
I would drive my 1978 pickup truck so fast I would get red-shift as I drove near the speed of light. Sometimes I would arrive before I left.
One day, I was driving along at about 280 MPH and this road about 1 mile long came in front of me. There was nobody around and I was thinking "Oh man I can really boot it". But something grabbed me on the back of my neck and told me to drive the speed limit. This was on a Saturday, nobody around, nothing except 3 solid minutes of sloooow driving at 25 miles per hour (that was the speed limit on this road).
Half way along, I really began to think how odd it was that I was forcing myself to do the speed limit, so slow as it was, along such a long straight road. I NEVER drove the speed limit when doing deliveries.
At the end of the road, parked behind a school, was a cop just waiting for demons like me. I would have lost my licence, probably my truck (which was only worth about $23 at the time anyway), and the result would also have lost my job.
It wasn't luck. I felt a clear and distinct "hair of the back of my neck" feeling and almost heard the voice tell me to go the speed limit. 25 mph.
