WOW . . . no mistaking THAT front end. I was up the hill, at a Herbal Life warehouse, returning home. There before me, going the opposite way was a silver one ... manufacturer plates. So as not to scare the driver, I waited until he'd turned the corner. THEN I blazed after him. Driver looked no older than 30. He turned into a ware house parking lot. I followed and got up within 30 feet, hoping he'd at least roll the window down. NOTHING. He did a 360 circle 2 times, then into an enclosed area. Funny location for a manufacturer's car. But all over, I saw converted SUV hydrogen vehicles with the local AQMD (air quality management distric) logos on them. some were in disrepair. Warning signs all over regarding oxidizers, propane, etc. Oh well . . . . although it was WAY cool, I had my phone camera out & managed to miss my golden oportunity to click off a few shots.
