FORT MORGAN, Colo. — For the last decade, Somali refugees have flocked to this conservative farm town on Colorado’s eastern plains. They’ve started a small halal mini-market and a restaurant, sent their children to the schools and worked at a meat processing plant. As much as Fort Morgan’s small town feel reminds many of their rural villages back home, some say they will feel like outsiders until they get what has so far eluded them: a permanent mosque.
