GANGS - Gangs in the Valley: An overview | Walla Walla Union-Bulletin

GANGS -"Valley's two most established gangs are 18 Street and Florencia 13. Most 18 Street membership/affiliation lives within the city of Walla Walla. Most Florencia 13 membership/affiliation lives in the Milton-Freewater area.
Both of these gangs are Sureño-based, meaning they emulate Southern California Hispanic-style gangs. They use the color blue as their gang color. They will display this in the clothing they wear and the handkerchiefs they carry nicely folded and pressed. This is referred to as their 'flag.' If a subject is displaying a flag in this manner, chances are pretty good he or she has been accepted into the gang by being jumped in.
18 Street and Florencia 13 rival each other. Both gangs are involved in assaults, graffiti, drive-by shootings and narcotics use and sales. We estimate 18 Street has approximately 200 members/affiliates locally and Florencia 13 has approximately 100 members/affiliates"
