I've seen all three gangs in seaside. Back when I was a little youngsta i had a homie named james that lived in Seaside but he went to school with me in Salinas. I used to kick it in seaside alot and like Doom said you won't really see anything there, except if you know where to look. If you go down to by where the adult bookstore is across from the fairgrounds in North Monterey you'll occasionally see X3 tagged up but I never saw them post up over there and I never saw any sets tagged up either. Dooms right on another thing too, that is that the homeboys from NSS ( North Sea Side) look like some straight up scraps I dont know why but they do. At the last car show those fools were getting hit up left and right by the homeboys. From my experience there when I was young it never seemed like the mexican gangs there even knew what was up. I knew three fools Earnesto, George, and Barney my homie james had told me that they were scraps. when I first met them the first thing they said was "I didn't know they let whiteboys be busters" long story short george had a fat black eye after that. After that they switched and decided to be homeboys. I didnt see them much after our first confrontation but when I did see them they had become some solid homeboys. From stories I've heard since then i've learned that there is alot of hood hopping in that city. The crips are down as fuck and are very solid though.
