Green Festival is the largest sustainability event in the U.S., with speakers, how-to workshops, music, organic eats and drinks, and displays from eco-friendly businesses and nonprofits (including, of course, Grist). Progressive luminaries strutting their stuff onsite will include Ben Cohen (of Ben & Jerry's fame), Amy Goodman, Hunter Lovins, John Robbins, David Suzuki, and Alice Walker. (Check out the full schedule for details.) The whole shebang will be carbon-neutral. About 30,000 people attended last year's Green Festival in San Francisco.

If you aren't one of the ticket winners, we can still get you in free if you volunteer to work a shift at the Grist booth. Email for more info.

And, if you're going to be in the Bay Area on Nov. 10, be sure to come to our reader party in San Francisco. Organic booze, door prizes, witty banter -- pun will be had by all.
