Why is ther so many armenians in glendale california?

Many Armenians started off living in East Hollywood (Little Armenia), I know there was a community leader who opened a community center type place over on Vermont Ave many many years ago. So Armenians new to the country moved to where other Armenians lived, which makes sense. Why be alone in a foreign country, especially if you don't speak the language, when you can live in a neighborhood full of people who are like you, with Armenian businesses, churches, and schools. As more Armenians moved here, they started expanding their community to nearby areas, including Glendale, La Crescenta, Pasadena, and Burbank. Armenians tend to have a close community, even with those that seem totally Americanized (2nd generation), many still attend Armenian community functions, prefer to date/marry other Armenians, send their kids to Armenian schools, and learn all the traditions.
