So I've decided to sell the car, and find another one, a pickup truck. The person set to buy the car is dedicated to keeping it running on veg. (We cleaned out the tank together, a nasty but necessary bonding experience.)
I go on tour till mid November, and am hoping to look for a diesel truck to convert in Texas, put a camper on it, and create a veggie powered mobile living unit.
In the meantime I will be getting around on a supersonic hoyakuza transport system, invented by my friend Yoshi Takemasa:

Stay tuned for more adventures.
