(Reuters) - It is hard to sleep at night inside the tent city at Oceanport, New Jersey. A few hundred Superstorm Sandy refugees have been living here since Wednesday - a muddy camp that is a sprawling anomaly amidst Mercedes Benz dealerships and country clubs in this town near the state's devastated coastal region. Inside the giant billowy white tents, the massive klieg lights glare down from the ceiling all night long. The air is loud with the buzz of generators pumping out power. The post-storm housing — a refugee camp on the grounds of the Monmouth Park racetrack - is in lockdown, with security guards at every door, including the showers. No one is allowed to go anywhere without showing their I.D. Even to use the bathroom, "you have to show your badge," said Amber Decamp, a 22-year-old whose rental was washed away in Seaside Heights, New Jersey. CONTINUE . . . FEMA has proven it is very good at one thing. Treating citizens like prisoners.
