Magna Entertainment had owned the Meadows track until 2005, when it sold the facility to Cannery Casino Resorts, which operates three casino-hotel complexes in Las Vegas. MEC took back a contract to run racing operations, while Cannery built and operated the slot machine facility. (It's unclear which entity is responsible for the only bowling alley at a US racetrack, which is scheduled to open later this summer.)
If MEC Pennsylvania does default on its contract as a result of the bankruptcy, Cannery would presumably take over the whole show.
More details to come, as well as a look at what's been happening in the main show of the MEC bankruptcy case.
