I'd would love to stand in the "free speech zone" with a sign that had offensive, inflammatory, incendiary language directed at the government on it. Hell I'll hold up a giant picture of GW with a Hitler moustache and dress in full nazi regalia. HEIL BUSH, HEIL BUSH

If you are willing to do this ..... I am sure the president will be in your neighborhood sometime.

I'd be glad to do it in the "other" free speech zone... AMERICA

Some of those ideas sound pretty wacky to me, but I think I like the business card sized signs on toothpicks.  You could get a bunch of GI Joes and have them hold the signs.
