[Michael Pliska]

Yes, Stefan was Bill's son, and they run DTT. He was a "Jr parent" as well, and I always assumed that was his daughter, but just learned this weekend that she was the daughter of his then-girlfriend (they split up last year). He was a great dad to that girl whether they were related by blood or not.

They announced that there will be a memorial service and parade lap in Stefan's memory at the Mission Raceway LODRS event in September.
