Professional protestors. .....most of whom haven't bathed since they disgarded their clothes and ran around in the rain at Woodstock (in '69).
They are also dumbed down. At least guys in the 70's would have said "I'm here to party", or "I'm looking for girls".
maybe they should get bussed down the coast to florida, at least hurricane Frances would scrub them and afterward they can do something useful, like help with the clean up.
