I've used a similar one before.
ATC: XXX, you've just been through the Kilmore gap, what was the weather like there?
Pilot: Yeah I think it closed in behind me, I wouldn't recommend anyone trying.
(Code for: Cloud was 200ft, I was skud-running all the way)
Maybe you have to be at 200' to fully appreciate the Kilmore Gap. We flew through there last Saturday - looked like the Kilmore
Basin to me!
