Very cool story...

David Plummer formerly of Westmoore HS qualified for 100M Backstroke. At age 30, it will be his first Olympics.

As far as I'm aware, he will be the first Oklahoman to swim in the Olympics.

He swam in college at Minnesota.

Well, Jerry Heidenreich was born in Tulsa (although live most of his life in Dallas). Swam in Munich. And if you count synchronized swimming, we had someone in London in 2012 I believe (her name escapes me).
