I'm well aware that Care has 911 contracts in both Orange County and LA County. That doesn't necessarily mean, though, that if they hire paramedics that the paramedics will be working in Orange County. Besides, what's there to help with? A 911 call in OC is like a circus rolling into town (I just love the fact that OCFA in Irvine dispatches their own engine and an ambulance to a call but still has Doctors to transport for them) with the fire engines being clown cars. There's already too many providers on scene and any difficult questions will be sent to medical control anyways (anything worse than a sneeze requires the medics to contact med control and give a full report over the radio).
Little story to illustrate the above. I had an incident when I was working as an EMT at Wild Rivers where a young girl was assisted to first aid by her parents after bumping her head coming down a kiddy slide. Patient's A/Ox1 (name, didn't know location, purpose, time) and extremely lethargic. 911 contacted immediately (I don't screw around with altered patients in a non-transport role). Long story short by the time fire arrived the girl had improved to A/Ox4 and just dazed. Fire's response was a battalion chief (who was "in the area"), a "paramedic assessment unit" (read engine), another unit which had paramedics on it (canceled en route, probably a fire department ambulance), and Doctors ambulance (private). That's 4 vehicles responding to an incident that should have required, at most, 2.
