Stop in for a cup of coffee

I keep lookin' , but I don't see a Christmas Tree. :wtf: are they usin' to start them races? The guy on the start line doesn't seem to use any obvious hand signals.
He has a head light on that flashes for them to go... it's basically street racing on a track, but that track..just holy ****.. the left lane hasa a huge dip bout 80ft out that keeps making people loose
