Be careful to watch out for the gang affiliated drift racers. Most often they drive really flashy cars, play loud music, crazy hair styles. If you aren't careful you might flirt with the wrong girl and get pulled into an underground scene and forced to learn how to drift in a car gifted to you by a rapper, such that you can win a race and take a bounty off your head. Dangerous stuff.
If you see a heavily muscled bald guy driving a Charger, befriend him. Knowing him and the connections that will bring will be highly beneficial to you later when you come back to the states.
