Are you the same person as GburgNatsFan?
Just have someone nearby read off imaginary boarding announcements. People attend telecons all the time from departure lounges.
I can skip the imaginary announcements. I travel at such an insane pace it won't matter aside from reducing the ambient noise levels. Granted should we play on Friday, I'd rather not have to explain why chants of "Let's Go Nats!" and "Cardinals suck" appear in the background of my part of the conversation during the monthly team meeting.
