Folks can draw arbitrary lines however they want. And argue till the cows come home. But they won’t necessarily win any arguments.

My hood – UC as an example. South UC (south of Rose Canyon, north of 52, between 5 and 805) is mostly older (1960’s) single family homes. North UC, aka UTC, is mostly condo’s, business, and shopping. Demographically – they’re not the same. But we share a fire station, high school and middle school, community planning group, etc.

I could argue that UTC is not part of UC… but what’s the point? From a technical point of view – we share services and schools, so we’re all one big happy University City.
