QCD was grandfathered in. Something in the law says a track in a county bordering the mississippi that conducted live racing in 1987 or something like that can operate OTBs and as an Intertrack location (technically it's an Intertrack location, not an OTB - 1.5% surcharge instead of 2.5%)
Yes -- the law is crafted with an interesting deftness. It's actually a pretty nice facility -- you can even head outside and see the remnants of the old track and toteboard.
Best,
