I may not get there with you, but a coalition of activists will gather at a coal plant near Capitol Hill on March 2 to carry the word that coal is dirty, unhealthful, and completely tied to the old, unsustainable way. 

I got word of the action from Bill McKibben, the author and activist, via Project Laundry List, of which he is an advisor. Here's what his missive said, in part:

It's time to make clear that we can't safely run this planet on coal at all. So we feel the time has come to do more--we hear President Barack Obama's call for a movement for change that continues past election day, and we hear Nobel Laureate Al Gore's call for creative non-violence outside coal plants. As part of the international negotiations now underway on global warming, our nation will be asking China, India, and others to limit their use of coal in the future to help save the planet's atmosphere. This is a hard thing to ask, because it's their cheapest fuel. Part of our witness in March will be to say that we're willing to make some sacrifices ourselves, even if it's only a trip to the jail.

The Rainforest Action Network has an organizing site, if you're going to bus down so you stand up and be counted.
