It is really quite easy you see.
Take the kids on a hike down near the *Secret Place*.
Once there they discover rocks, water, sticks, ...
and imagination takes over.
They begin to make plans to build a dam, or perhaps a 'fort'.
Rocks are very pretty, they decide on which ones to take home and show their moms.
No fighting over toys.
No ringing phones.
No cell reception.
No computers or computer games.
Imagination at work only.
Just sit back and let nature do its thing.
Kids doing what kids should be able to do, with fresh air and exercise as a bonus!
