This handy resource presents a 'village' community who, in post-apocalyptic times, have settled down to make the most of what they can scavenge, creating a life for themselves amid the ashes of whatever catastrophe wrecked the 'old world' they used to live in.
Some things - like scrap metal - they have in abundance, as the settlement is built on the ruins of an industrial area. Food, however, is hard to come by, and hunting is using up precious gasoline! Their competent mechanics and tinkerers are glad to trade with passers-by, services or scrap for food and anything else they have to offer. They have limited power from some rather battered solar panels, and are experimenting with a more effective power plant.
Rather 'Mad Max' in flavour, this will be a useful settlement for your characters to visit as they explore your post-apocalyptic landscape - or they may even settle in here, perhaps (knowing your average player-character) trading their skills as defenders or explorers for a place to live.
Everything is concisely but well-detailed, there's a lot for you to draw on as you make Scrapper's Bridge an integral part of your alternate reality.
