Where do the Socs like to hang out as opposed to the Greasers?

From the text:

Then we went across the street and down Sutton a little way to The Dingo. There are lots of drive-ins in town--- the Socs go to The Way Out and to Rusty's, and the greasers go to The Dingo and to Jay's. The Dingo is a pretty rough hangout; there's always a fight going on there and once a girl got shot.
