Stephen Von Worley pits the country's 12,000 McDonald's restaurants (black) against the 24,000 other major fast-food joints (non-black):
[E]ach individual restaurant location has equal power. The entity that controls each point casts the most aggregate burger force upon it, as calculated by the inverse-square law – kind of like a chart outlining the gravitational wells of galactic star clusters, but in an alternate, fast food universe. By far, the largest pocket of resistance is Sonic Drive-In’s south-central stronghold: more than 900 restaurants packed into the state of Texas alone. Sheer density is the key to victory!
