September means auto trade showtime in Detroit with the Automotive News World Congress, Management Briefing Seminars and MOVE America. It's a time of insanity for both reporters and PR people but also an opportunity for a goldmine of stories and coverage. Host Ed Garsten runs down the shows--everything from signing up for credentials, wondering where to park, landing coverage for PR people, managing the volume of material for reporters and waxing nostalgic about a big yellow tent, wrinkled backdrop and fruit smoothies from the past.
