After an exhausting two day hike through Shoshone National Park, in Wyoming, you've finally made it to your firewatch tower.

You've taken the job to escape from your life back home, and saw an opportunity to do so when you spotted the ad in the paper.

Clambering up the stairs of the fire watch tower, you stumble inside, exhausted. Flipping a switch on the wall, the sound of a generator out the back on the ground is heard, as the lights flicker on.

And then, a feminine voice calls out.

"Hello, Two Forks Tower!"

A yellow radio is sat on a charging port on a desk in the tower.

You pick it up.
