Actually the San Fernando Valley is very diverse I'm all over the place every day, I see all types of the good, the bad and ugly in every corner of the Valley, more of the good thank god!, I am a Hispanic non gang member professional with high expectations and a quality business,I live in Sylmar, right at Polk and the Old San Fernando Road, my neighborhood is clean (not perfect) but clean and has been safe with good, quite neighbors, never had any problems for the exception of one household of some druggies (tweekers), they stand out from everybody else because they are all around 50 years old, up 24/7, nobody works, they sit in front of the house drinking all day, a there's lot of in and out traffic to their "place of business" unclean yard, beer bottles, etc. and they are the only white people on that half of the block.
Ive seen it all, Asian and white gangs in Granada hills and Santa Clarita, Lake view terrace blacks, and many areas of the Valley including Sherman Oaks, Encino, etc. infiltrated with white gangs, tweekers, and not so clean homes, I also see portions of Pacoima that are real bad but some parts that are OK, East San Fernando and around the East portion of Maclay have some of the most interesting homes,that are clean and have the most beautiful architecture in the Valley.
Area from area you find the same thing in all parts in this Valley of ours, it's just not a Hispanic thing.
