In LA we used the Woodland Hills hall which was sold in 2004 for 20 milion plus..
We also attended a small old theater in Crenshaw which had a cafeteria and KH in the back and a small park like island in the front, as a kid we used to go to the Thrifty store, which was on one of the sides of the hall, to buy all kinds of candy and gum, the assembly commity always discouraged this but no one ever listened. This thearter got sold 10+ years ago.
Many in the LA area now go to Mira Loma (btw 60 HWY & 15 INST) (beautiful hall) for the circuit assemblies which is relatively close to the Norco hall and therefore also smells like cows.
District assemblies are held at the Long Beach Convention Center.
