Sorry that you missed it godlike. We had put up signs, did you not see them? It was slightly off of Phinney (half a block), but in the Phinney Ridge community center as described.
The event went really well. About 175 people showed up and there were at least 50 TDIs display. Mostly A4 Golfs and Jettas, but there were also some A3 Jettas, and couple of B4 Passats (including one wagon), a VW Transporter with the 2.4L NA diesel engine, a few Mercedes, a few Rabbits, a Hummer and some other trucks. The forum itself was packed and there was standing room only during the talks. There was a nice demo of making a small batch of biodiesel and Drivbiwire demonstrated timing adjustment on my A3 Jetta and talked about the differences between the A3 and A4 engines to a small group and talked about the benefits of running biodiesel to the entire forum. Dr Dan was there and sold almost 200 gallons of fuel (more than he brought...some people had to go back to his shop).
Others took better pictures than myself (I was mostly paying attention and not photographing), but a couple that I took are online at
