Phantom Of The Tree

On a walk in the park with the wean, he gravitated to the usual tree, beside the artificial lake with its flotilla of ducks. Underneath its a cage of shadows, and there are usually other children running about or climbing. He met this pair, brother and sister I presume. I took this with the parents' permission, but didn't intend to post it till I realised how striking it was.

I was thinking of making THIS ONE the blip.
