INDIANAPOLIS -- Indianapolis 500 hopeful Stefan Wilson joined other IndyCar drivers Friday night for the Festival on Main Street in Speedway.
Over the past year, Wilson has been on a mission to promote organ donation in honor of his brother, the late IndyCar driver Justin Wilson, who died during a race in Pennsylvania last year.
Wilson says this past year has been the hardest of his life. But through it, he's found an unexpected passion.
"Before last August I knew very little about organ donation," Wilson said. "Never even came up in conversation. Didn't even know Justin was an organ donor until that time."
Justin Wilson may have died, but his organs were used to save the lives of five people.
"Having gone through what we went through, the act of being an organ donor that Justin chose to do was something that we could really focus on as a positive," Wilson said.
In the midst of the evening's festivities, Wilson gave autographs and took pictures with fans – and, he hopes, future donors.
"I would hope that if either of my children needed something … I would hope that something would be available," he said.
Wilson will work next week to qualify for the 100th running of the Indianapolis 500.
