People in Long Beach are MUCH more casual and laid back than people in LA and Hollywood. People are not as pretentious and flash their money around (as much). Most people are into the casual and comfortable look with jeans and a nice shirt. Pretty much anything and everything goes in Long Beach. The yuppies hang out in Belmont Shore. The corporate people hang out on Pine Ave. The tourists tend to flock to Shoreline Village (but, so do the locals). The artistic types hang out in parts of downtown Long Beach. The gay crowd hangs out at any one of the many places dotting Broadway.
Christmas in Long Beach may not be white, but the city has its own traditions, such as boats(like this one) decorated for their Shorline Boat Parade.
