Portal to a park bench

One simply cannot travel back in time to change the future outcome. But one may travel in to the void beyond, that has not  yet been seen, only to lay a trail of crumbs for one to find. Hints and clues a mystery if you will of things that only one will understand. Like a warm June evening with the wind blowing through the leaves, causing the midday sun to pass through them, and shine upon a hill top, with the sound of the lake at the bottom splashing against the rocks.
The future is but a string length away and every event and every moment can be added like beads in specific locations to mark each spot and destination. And as it comes together creating that perfect circle of unpredictable things to come, and opening the portal to a bench placed on a hill in a park.
