Hi Andrew, I would love to take that class ! I am too far away and I don't like to fly anymore.
If I could make a batch of biodiesel with anyone in the whole world my choice would be to make a batch with you, Tilly and greengirl ! You and Tilly are both invited for a Florida vacation anytime, on me !
I think you are the real deal. 
Keep up the great work !
Thanks, Steve
