Excellent Tom!

It would be nice to independently corroborate your recollection but
that does sound very likely.

So the next question is why is she stuck to a fence post at Serene
airstrip...

Mike Stringfellow looked at an official airport database record for
that airstrip. The record indicates that there are two single engine
aircraft based there and one "operational glider" based there.

Perhaps then the owner of Serene had acquired 71JR from Mr Reid's
estate for personal soaring endeavors. Maybe a thunderstorm came
along one day when she was not tied down adequately. I'm thinking she
may have cartwheeled in the wind to her final resting place skewered
to the fence.
