Linda:
In Ask Linda #489 you wrote: "Perhaps a better way to
remember this is that a ball is on the golf course (not OB) if any part
of the ball touches the course."
Exactly, this alternate wording of the OB definition makes
it consistent with the definitions of ball in a hazard, etc. I've always
wondered why more instructors at rules seminars didn't point this out. Kudos to
you for doing so.
