Race car insurance

This hit my funny bone hard. LOLOL
It seems like it is not only becomeing more available , but very affordable.
I recall " key on " race car insurance being pretty pricey , but this is something I will look into.
I had Hagerty when it was still a street car and it was really cheap I thought.
On track is still available , but still not cheap.
But Hagerty had issues with roll cages , tubs etc. that they seem to have gotten over.

Where is it that you get race insurance? I looked a while back and could not find anyone that would cover the car in motion on the actual strip from green to stripe.
