Raiders of the Capital Shitfield

Raiders are Mexican immigrants who immigrated by digging wholes through the border (the guarding was handled by greasy Enclave fatboys) just before the Great Fart that destroyed the world. They acquired the super age of ghouls without the skin turning to shit because they were so hairy. Now they wander the land using shit weaponry and rusty armor. Throw sticks at them and watch them explode.
