All true, but Simi isn’t in the Valley. Chatsworth, Reseda, etc., are essentially named neighborhoods in the city of LA (with some political autonomy), but Simi Valley is a separate city (incorporated in 1969) in a different county. It can’t ever have been part of the city of LA.
That is right. I was trying to come up with Fernando Valley, but could only tickle the brain cell that said “Simi Valley”.
I might be because I used to drive through San Fernando Valley on the Simi Valley Freeway, on my way to Camarillo Airport.
but you are right, it wasn’t Simi Valley, but San Fernando Valley.
