It definitely depends on where you're flying.
While flying in the USA, I planned a flight from Phoenix to Los Angeles. It was the longest flight I've ever done, into an area where I'd never been before, where the air-space is extremely complex. Many hours of planning went into the flight, but by the morning of the flight, I was feeling confident.
I called for a briefing. The only significant weather was sand-storms, with vis down to 8 miles, and light to moderate turbulence. Quick conversion to kms, and I realised that 8 miles was well above my minimums, and the turbulence wasn't going to bother me, so I was set to go.
Well, 8 miles of visibility certainly isn't any problem flying around south-east England. But flying through the Californian desert, where visual navigation consists of heading from mountain to mountain, with each significant mountain around 30 to 40 miles from the next, was a little harder. And a bit of turbulence may not bother me when I know where I am, but I could really do with being able to write on my chart and on my plog without having the pencil knocked out of my hand at a time when I'm finding navigation a little tricky. It's the only time in my VFR flying career that I've had to absolutely rely on navaids for navigation. Fortunately, I had already planned to use navaids for backup, so I had all the details on my plog and chart before the flight. So the trip, although stressful, was safe, and I arrived at Los Angeles very tired but in one piece a few hours later, and a much wiser pilot.
