The RCC is adjacent to the Office of Emergency Management, in the Hein Building on Route 648 in Glen Burnie. They were in the RCC due to work being done at Headquarters. May be back by now.
Wasn't there a new EOC built in an old theater in The Burn, and some sort of regional backup center adjacent to it? Seems like they spent a lot of money on it back in the early 2000s.
