Just FYI, they were 450 or 460MHz simplex, all listed as temporary licenses in the FCC database & licensed/published in late May or early June.
Based on the FD/EMS Comms at the event, insure would have loved to hear the event ops & security channels as well as the Tac channels LVMPD used.
I didn't bother to monitor the LV speedway trunked sys to see if they were involved much with the event.
