San Diego Bridge
Raiders of various sorts used to run rampant throughout the city and surrounding areas. Over time most of the bands either settled down or (more likely) killed each other, leaving a swath of looted buildings and pillaged families.
One settlement that was never successfully raided was the San Diego Bridge. Spanning the bay between the city peninsula and the mainland, the towering bridge had only two easily guarded entrances, and had an easy path to the sea for food. After the collapse, the bridge became an effective fortress. It also became known as a decent place for nearby farmers to sell their produce for shoes, batteries or other salvage.
The San Diego Bridge became a haven for some time, but due to overcrowding and stagnation, it’s become an inhospitable place to live. The stench of rotted fish pervades the senses of any who enter, and new, young gangs will rob or swindle anyone they can corner, as entrance guards do not allow visitors to carry weapons.
