I'm wearing a Hawaiian shirt today. Is that close enough to being there?

>I'm starting a new job in Hawaii on Sept 2nd. Obviously I'm quite exicted about it - but also a bit freaked-out as I've never even been to Hawaii before. The job is on the Oahu island in Honolulu. Anyone out here from Hawaii? I know Rick S. from west-wind is out there, but looks like he's on a different island...
