Here's a reminder that the Green Festival will be hosted at the Convention Center in Washington DC this weekend (September 24 & 25). You can get tickets at the door for $15. If you ride your bike to the event, you get $5 off admission, and you'll receive valet bike parking service (for free). You can check out all the D.C. exhibitors here. There will also be guest speakers, food samples and movies screenings. I'll be there too, covering the event with gusto. :: Green Festival D.C.
