How many hands have you got? Glad you have bio-diesel out there. Here we're a good decade, maybe two, behind you. And with all the fried foods they eat in Florida, we're literally swimming in something we could be burning in our cars.

The thing I've noticed here in Florida is the huge jump fossil-fuel diesel has taken. The Shell station at Calle Ocho & I-95 -- a landmark spot -- had regular gas at 3.49 and diesel at 4.39! That would somewhat negate the effect of the better mileage one gets with a diesel car here.
