When more than 8000 INTA members arrived in Seattle in May, 2009 we were ready with 3 photographers working for 5 days.
We supplied photography for a daily newspaper, website postings, and a digital slideshow on CD for the members when they got home. Most of the event was at the Washington State Convention Center. A large finale party was held at the Museum of Flight south of Seattle. There were more than 5000 at the party.
