The Indy Racing website has 620 listed as an affiliate. Hopefully, that's the case, as I much prefer the radio announcers to the television. They've always been top notch, going all the way back to the days of Sid Collins. BTW, if you are an Indy fan, go to WFNI's website, this Saturday night, and they will rerun classic 500 broadcasts all night; usually one from the '50s/'60s, followed by a more recent race. I think this year it starts later, due to a WNBA game.
