Been seeing Rosie's inferno pizza popping up at alot of the music festivals my band plays at in Southern Oregon. They do a great job and are the best pizza vendor I've had at any of the summer music festivals I go to (and I go to ALOT)... Check out there mobile pizza rig, its pretty sweet. I watched the crew prep everything from scratch in the morning at a festival last year, and it shows in their product.
