Rivals

We, the people of Busker County, blew Morgantown off of the map.
Well, sorta.
It started with a friendly football rivalry, but within a week we had armed militias running around, burning crops and the post office.
Someone suggested that we hold a football game to settle our differences, but it turned out to be an ambush.
Rumor was that Morgantown was working on a nuclear weapon.
Turned out to be true, but there was a slight glitch and they blew themselves off of the map.
Call it an error if you want to, I’ll call it peace and quiet.
