Central Concrete Supply Co Inc is a concrete factory in West Oakland. It's also labeled "Walker's Concrete" on the building. The factory compound includes two ominous towers with busted windows, faded paint, etc. The compound walls are made out of ancient-egypt-style concrete blocks - blocks which are highly likely to have been produced in the factory.

A lot right next to the compound has a trash pile and a graffiti wall. Across 26th is a mural by Deb and a large Mark Bode mural.
