Background
On October 30, 2077 Lavonne called the foreman; it was strange for a few reasons, the first was that the last time they spoke, it was at a military briefing in Portland. The second was the call's subject was about her nephew's baseball team. It was some sort of code, she was trying to warn him of the impending incoming nuclear devastation. In her words, "Sending the team home to be with their families." He followed her advice and managed to not die in the bombardment himself.
