Nice!
I wanted rockery rock once and I was visiting Ma-in-law. She took me to a quarry that had beautiful white rocks. He said help yourself and I couldn't resist. Ended up with close to a tonne of the stuff in the car, then had to drive 450kms home again!
I suppose I used a load of fuel, but the truck drove really well. The headlamps were a bit high for the last dark hour of the run, but otherwise it was great!
