2120: The Blue Light
I traveled to May 28th, 1978 to see The Beach Boys, Linda Ronstadt, and Dolly Parton perform at Oakland Stadium, and it was everything I hoped and more! Then I prevented an apocalypse (you're welcome), and traveled to what I thought was the 90s but turns out I went a few years too far (I'm still getting the hang of my newest time travel contraption) and found a bunch of ruins and no people, just plants taking the Earth back. It was peaceful.
