bobla - I might have mentioned this before, but Ron goes back a long way in this game and has well placed senior contacts (comes with the years) "in-the-know" in key organisations - they're an incestuous bunch - and he's held in high regard.
Ron didn't just pluck this Canning idea out of thin air. There's a significant body of technical survey records of varying quality that go back many decades in various WA archives - such that only those senior networks that have been around for similar periods of time really appreciate.
