Basic Nature Lighting

I've searched these and other forums and can't find an answer to a basic question.

Some facts:

• I'm using Unity's free version.
• I'm looking to light an outdoor nature scene with natural sunlight.
• I have 0, zero, notta, zilch, artistic ability.

I know I should use 2 Directional Lights, and something about inverting them from each other.

But if someone could just post what values I can just copy and paste into the settings boxes for just a very basic nature scene lighting. Nothing fancy. Just going for a nature hike at 3pm on a sunny afternoon.

I will be forever thankful.
