Atlantic City Lights

Decided as part of my Wings refresher training to dust off the night flying
skills and give them a once over. I am based near Philly and flew to
Atlantic City (KACY). As we were approaching from the NW I noticed a bank
of very large and bright floodlights pointing back toward me. They were
about three miles to the West of the field. They really screwed me up as
they obscured the visual approach by washing out the field light, despite
the distance.

Anyone from that neck of the woods know what the heck those lights are (they
definately aren't from the casinos as they are too far away)?
