From an email-A28.org:
George Bush and Dick Cheney have lied the nation into a war of aggression, are spying in open violation of the law, and have sanctioned the use of torture. These are high crimes and misdemeanors that demand accountability. Since Congress doesn't seem to get it, on April 28 Americans from Miami, Florida to North Pole, Alaska are going to spell it out for them: IMPEACH! It's time to say NO to impunity for lying, spying, and torture.
They are a grass-roots organization, and are organizing events all over the country.
Let's put the word IMPEACH! everywhere on April 28. If you're in Miami you'll be able to voice your opinion directly to George Bush himself. If you're in San Diego you can tell Nancy Pelosi to put impeachment back on the table. And if you're in Cleveland you can give your support to Rep. Dennis Kucinich, who is considering starting the impeachment process. Here are just some of the actions people are planning. Please sign up for one of them...or start one yourself! If you don't see your community listed and want to find people in your area to team up with, post a message in the new ImpeachSpace Forum.
Sounds like a good idea to me.
