Some of Washington state's biggest political names, including Gov. Chris Gregoire and Seattle Mayor Greg Nickels, stuck some spades in a ceremonial sandbox today to mark the latest construction phase of Amazon.com's new office campus in South Lake Union.

Noticeably absent from the event, however, was Amazon CEO Jeff Bezos, or any other top Amazon executive for that matter.
