The North Carolina resident drove to Indiana so he could share the moment with his late father, a World War II Navy veteran who died in 1980.
Williams camped out by his grave with a "W" flag to honor a promise he made many years ago.
"I talked it out with my boys forever. I let them know that I told my dad—we had a pact," he said, per WTHR's David MacAnally. "When the Cubs—not if, when—the Cubs got into the World Series, we would make sure we listen to the games together."
While the committed son traveled across the country to hear Game 7 in a dark cemetery, Williams said that his father, "a hell-raiser," might have been too preoccupied to follow along.
