Similar incidents have happened on this coast. A couple of years ago they busted several that were gathered in a private business parking lot in Norfolk, Va. It started out with a handful of relatively quiet, respectful, law abiding gearheads gathering, and then the ricers and street racers started filtering in disrupting the business, leaving trash everywhere and driving recklessly thru the lot endangering customers. Some nights as many as 150-200 cars. Several would go there to meet, and then go to nearby I-64 to race. Some vehicles were confiscated.
