California, you'r e in luck. There's biodiesel events pretty frequently in Northern California and a few in So. Cal as well.
I run a list which is only for announcements of California biodiesel and SVO events. I'ts at
www.groups.yahoo.com/group/norcal-biodiesel-events. There's a free event tomorrow night in San Francisco and a not-so-free biodiesel homebrew class this Friday in Hopland and an SVO class on Saturday in Hopland. Go to the link above for more classes. If you're in Southern California, there is also a biodiesel list for So. Cal which sometimes lists classes I miss on the Norcal-biodiesel-events list. ALso, we have a discussion group for NOrthern California biodiesel which might be hard to find- it's at
www.goblin.punk.net/mailman/listinfo/burnveggies .
Oklahoma- I'm planning a Midwest tour for the fall, and I could probalby do something in OK if there was interest.
Thanks, guys!
Mark
