As a previous poster pointed out, it really all boils down to what
level of risk you are willing to accept, as well as your comfort level
and level of experience.

I live and fly in northwestern New Mexico, and frequently fly XC across
northern Arizona and up into Colorado with my family. If I subscribed
to the rule of never flying and night in the mountains, I'd never be able
to fly at night. (Mind you, I fly a PA32-300, not a Cessna 150,
but it's still a normally aspirated single-engine).

However, even as an instrument rated pilot, I will not fly at night in the
mountains in IMC. The MEA's are just too darn high around here (16,000+),
and there isn't an "out" should something go awry.

Set personal limits and minima, and stick to them.

As a non-professional pilot, my my rule-of-thumb is that won't do any two of
the following three:

Night
Mountains
IFR weather (basically in significant flying in clouds)

All three is a huge risk
