Any luck hearing anything from where you were at?unless nhra has a repeater or a decent base station unless your in parking lot or next door you may not hear much.
I found the NHRA Race Control and Pit Control frequencies, and monitored them at the races at Pomona in March.
NHRA Race Control is 464.2875 and NHRA Pit Control is 452.4000. Got the list from Racing Electronics.
