Jackson County’s time capsule is sealed, entrusted to the Jackson County Historical Society for decades of safekeeping.

“You’re all invited back in 2093 when we reopen it,” County Executive Mike Sanders said during a brief ceremony Saturday on the steps of the Truman Courthouse on the Independence Square.

Harry Truman worked in the courthouse in the 1920s and ’30s, when he was a county judge. In those days, the three county judges served much the way the county executive and County Legislature do today. His old courtroom, at the southeast corner of the first floor, remains popular with tourists.

The idea of a time capsule came out of the renovation of the Truman Courthouse, which was completed last year.

“This building itself is something like a time capsule,” Sanders said.

“I would count this restoration of the courthouse on par with the restoration of Union Station and Liberty Memorial,” said Independence Mayor Eileen Weir.

Former Mayor Don Reimal echoed that idea.

“I would encourage you to make notes of what you do today,” he said to the dozens gathered for the ceremony. “Pass is to your kids, and encourage them to pass it to their kids.”

Officials put dozens of items into the time capsule, commemorating the renovation and suggesting what life was life in 2013: letters from local officials, baseballs, footballs and soccer balls signed by the Royals, Chiefs and Sporting KC; poems by local fourth graders; newspapers, brochures and books – and “not the least of which is a Twinkie,” Sanders said.
