Bob Jenkins, longtime Indy 500 and NASCAR announcer, has passed. He was great in the early days of ESPN with Larry Nuber on "Speedweek" and did excellent work on the "Thursday Night Thunder" USAC midgets and sprint car events. He once said he had never not had a job announcing something, either radio, TV, or PA, for the 500 at IMS since 1979. Diametrically opposite from the Hellzapoppin style of race reporting, his reporting was always just enough and always insightful. RIP Bob.
