I used Flora's megaphone to make a few announcements.
One I asked for a show of hands for anyone who considered themselves an "environmentalist". When they raised their hands, I said, "Good, now please pick up a piece of trash and take it with you."
Another announcement, "Your attention please, it is now mandatory exercise period for all environmentalists. I want every enviromantalist to bend at the waist, touch your toes and while you're down there, grab a piece of litter."
"I realise that George Bush is poisoning the planet, but could we please have the envronmentalists please come back and take their trash with them."
Normally the police are very diplomatic about laughing at jokes and seeming to side with a party to a "dispute" but on those announcements more than a few laughed.
LOL .. great announcements
