The one MavTV is running right now is listed as Toledo #2 but they are showing last year's finale at Lucas oil raceway.
Still might run the race today, check MavTV in the next 30 to 45 minutes. According to ARCA's Facebook page, they were trying to get the track dry for a night race.
TV listings don't get updated with last-minute race schedule changes. They bumped the start 6 hours earlier to accommodate weather, but it didn't work out. There was a rain delay after a caution in the first few laps. I switched off MavTV around 1:00pm or 1:15pm Eastern when they started playing a Lucas Oil Late Model Dirt Series replay as a filler. This is when it would help to have a subscription to TrackPass on NBC Sports Gold, so you can watch the race after the fact, whenever it happened. The "NASCAR Roots" subsection of TrackPass is pretty reasonable, only $20/year or $3/month if you prefer to pay more overall but have the convenience of monthly billing.
Anyway, nice to see ARCA live preempting the pre-recorded races on MavTV.
