I'll have to give FloRacing some credit after all. They did get back to me with a link to their archived races, which I'm now able to watch on my pc. As far as the current ones on FloSports, I see that all three nights of USAC sprints appeared on my Roku last night, although night two ends just as the feature is pushing off. As well, all the archived USAC races are still on Loudpedal's website for the time being, so I've been able to access them there. I hope that site doesn't disappear. All in all, it now appears that the subscription was money well spent.
