Washington International Horse Show

The Washington International Horse Show began yesterday and continues through Sunday at the Verizon Center. Here's what I found last year:

464.6250 [127.3] Inside Operations? (Channel 1) (R)
464.7250 [192.8] Outside Operations? (Channel 3?) (R)

In previous years, the organizers have used several more channels. Search the typical frequencies used by Bearcom Rentals (464.5000, 464.5500, 464.6000, 464.6250, 464.6500, 464.7000, 464.7250, 464.7500 and +5 MHz).
