TJ Fallon started visiting U.S. presidential gravesites during the height of the COVID-19 pandemic in 2020.

“I did it out of complete boredom after being furloughed from my job,” the New Jersey native said. Four years later, not only has he visited all 39 presidential gravesites at least twice, but — as of this week — his son, Henry, 10, has also seen them all. On Monday, Henry of Brick, NJ, likely became the youngest person ever to check off the feat of paying homage to every dead president after he and his father disembarked from their inbound flight to LAX to visit the Ronald Reagan and Richard Nixon libraries.
