When I was in Seattle recently I saw a small group of people with placards. It looked like they were going to a demonstration. So of course I followed them.
Their cause is a campaign to put a goldfish in the Seattle Aquarium. According to the protestors, the aquarium doesn't think a goldfish would be a meaningful addition to their collection.
You can read about and see Leonard on his website http://www.letleonardin.com. It's very cute, he's just swimming around his little tank, you can even click on some papers that tell his story. He even has his own page on myspace.com. There are other websites devoted to Leonard and his plight. To find them, just Google leonard the goldfish.
