Each floor of Club Graing is like a bar with its own crowd and personality. The basement is for CS/ECE majors hacking away in the linux lab and people who are completely buried in their textbook rather than facebook (and cell phone too because its hard to get reception down there). First floor is for non engineers who can't log on to ews computers and an eclectic mix of always stressed-out looking people on the west study area. 2nd floor open area is for people who like to read and take notes (i.e. not engineers). The crowd in the open area is pretty academically diverse, but the 2nd floor pink and green study areas, frequently populated by minorities, are not. No one really studies on the 3rd floor besides people who like to look over to the open 2nd floor area or when the library is completely packed. 4th floor is like a more productive version of Club UGL. It seems to be frequently populated by CEE students, but that might change when they get their own student center in the fall. If you stay there late at night (around 3pm), it becomes a gathering place for various ethnic groups where people either make beds and forts out of couches or have a WOW LAN party.
