Peeping through the tunnel towards the dry creek bed, a group of boys are busy loading up an array of work vehicles with rocks.
And then they are on the move! Over the bridge…
… and through the tunnel!
More loads gathered and on there way.
A delivery made …
… and more to come!
Some rocks needed here…
…and some sent down the slide.
Load up again, and back to the dry creek bed! All in a days work!
