The arrival of the Rose fleet is an annual tradition in PDX. At times, anti military groups have also been present at the arrival of the ships. I think this year would be a great one to let them know that instruments of murder and destruction aren't welcome in Portland. Perhaps the money that fuels these ships down the Willamette could be directed to Portland Public Schools. How many people are willing to be at the waterfront for a (certain to be unpopular) protest?
For those who think that the troops "are just normal folks caught in a bad situation" or my faorite: "just want to get home to give their kids a hug", perhaps it would be appropriate to have a banner with a hotline number to get advice on how to register as conscientious objectors.
