Last week, a few seniors were caught red-handed defacing the pavement in front of the Waterfront Park Community Center.

But the guileless vandals fessed up quickly: They were just reminiscing with a little “gradfitti.”

After tagging their years, they talked about their own graduations, decades ago, and their high school memories over apple juice and cookies.

“There were a lot of cliques in my high school,” said Gary Carter, Class of 1961.

“The group I was in, we were in a rock band. We never really got along with anybody else in our class.”

Instead, Carter’s crew pretended to be beatniks and took up midnight drag racing.

“I got done with [the mischief-making] by the time I was 30,” he said.

George Bussell, Class of ‘45, recalled his attempt to cancel Paint Night as the Bainbridge High principal in 1969.

“The first year I was here I thought, ‘This is terrible!’” he said. “They’re disfiguring the whole street and everything.”

But the green administrator was in the minority, he found out, when he tried to raise the issue at a school board meeting.

“One of the board members said, ‘Oh, it’s cute!’ Well, that ended that discussion,” he laughed.

Four decades later, with his own graduation year scrawled neatly in white block letters, he’s come around to the tradition.

“It’s wonderful!” Bussell grinned.

Per the city’s request, the street artists used a non-binding spray paint that dissolves with rain.
