Been almost caught myself and I didn't even realise the danger I was in until a few days later.
"Get home itis" heading back to Melbourne from Swan Hill. Just North of Bendigo the ceiling started to descend towards 1000AGL. I had the brilliant idea of pushing on and decided to head for Bacchus Marsh, overflying Daylesford.
As I approached Daylesford, I could see the ceiling over the mountains ahead dropped to a little over 500AGL by my estimate.
"Thats OK" I said to myself, "I'll just squeeze under and then fly down the Lerderderg Gorge" to Bacchus Marsh, then an easy coastal back to YMMB".
.....And I did exactly that....
..and found myself over tiger country, the gorge is very rough....with a very very low ceiling that was descending, not rising.
The next Ten minutes were exciting, and nowhere to go except forward. Luckily I just had room enough to descend a little faster than the cloud.
I should have either returned to Bendigo or gone further West to Ballarat and either landed or followed the freeway down.
Lesson : Unless you can actually see your destination, don't try and squeeze through.
