I flew 4,400 miles to Warren Buffett's big bash. Even after retiring, he's still the main attraction, and his legacy will live on.

On Sunday morning, I took an Uber to Buffett’s home, around a 10-minute drive west of the city. The investor purchased the house for $31,500 in 1958 and has resided there ever since.

I watched a steady stream of people arrive by car, walk around the investor’s family home, pose for a few pictures, then depart.

It struck me as remarkable that a billionaire’s home address is public information, and anyone can visit his leafy suburban neighborhood and try to catch a glimpse of him through his hedges.

Prashant Dugar and Anand Behl were posing for photos with their Buffett Squishmallow outside his home.

When I asked why they’d come, Behl joked it was like “asking why are Christians at Jesus’ birthplace.”

Buffett lies at the “intersection of human excellence and human values,” Behl said.

“You look for heroes in life, right?” Dugar added, noting that Buffett is one of the very few people in finance who make the cut.

The pair told me that Buffett’s choice of home speaks to his core values such as humility and frugality, his desire to avoid the noise and distractions that come with luxury and big-city life, and his long-term investing approach.
