🌾 Central Valley
- Norteños — Fresno, Bakersfield, Visalia, Merced.

- Fresno Bulldogs — independent, Fresno-centric, red/white, ~4,000 members.
🏜 Inland Empire (Riverside / San Bernardino Counties)
- Riverside 13 / San Bernardino 13 — Sureño sets.
- Crips / Bloods sets — Perris, Moreno Valley, Fontana, Ontario.
- Skinhead / white supremacist gangs — active in High Desert (Victorville, Hesperia).
⚠️ Critical Caveats
- Gang injunctions, RICO, gentrification, social media disrupt territories yearly.
- “Sets” = local cliques; loyalty to set > city-wide gang.
- Law enforcement uses CalGang database — controversial, error-prone.
- This info = awareness, not navigation.
California gangs: prison-born, street-expressed, constantly mutating.
