I lived in Antioch from 1972 to 1975. It was a totally straight square town then.
Depressing to find it’s gone downhill.
It has MASSIVELY expanded. Just before I moved there, I used to skydive at the airport. Remember where the airport was? Grassy hills for as far as the eye could see? All developed now with the usual generic suburban sprawl, all the way out to Brentwood.
