Driving even 30-60 minutes outside of most Australian cities will get you very dark skies.

But it's still a world of difference to go out somewhere rural, and preferably high up (eg northern NSW Tablelands) to camp under clear skies.

Even without drugs, spending too long staring out at those enormously bright stars can be a very trippy experience.

You can almost convince yourself that at any moment you could fall off the planet and into those stars.
