I have to agree with Duck Pilot.
I only did scud running over the mountains once and eventually had to divert to an airport (YCWR) in the opposite direction to where I was wanting to go (YSCN).
As the terrain was getting higher the cloud was getting lower, and daylight was fading earlier than expected. I knew I'd wandered off track and wasn't sure where I was.
If there hadn't been an airport nearby with a VOR and PAL I probably wouldn't have survived that very steep learning curve.
Fortunately I had a NVFR rating (but no CIR).
