New way to party .. on the FREEWAY !

So my friend told me about this last night.

Here is the CHP log. But my friend described it as a bunch of folks in their blinged out rides partying it up on the freeway near Hwy160 and the Capitol City Freeway, people dancing and music rattling with all traffic stopped.
