Both Friday night tracks, GC and Bloomington are good about calling off early when there is crappy weather to save fans and teams money. I’m usually, “believe it when I see it”, when it comes to rain. However, when it gets into the 80-90% range, it’s a pretty good bet it’s going to happen to some degree. That’s what it looks like right now. Just a guess, but I would say they would call it earlier in the day if it looks that bad. Hopefully it doesn't end up looking that bad.
