The chances you live within walking distance to a spy site are 100 percent for those living in the D.C. area, according to a former CIA official.
Robert Wallace, who spent 40 years in the CIA, wrote the book “Spy Sites of Washington, D.C., A Guide to the Capital Region's Secret History,” which details hundreds of locations in D.C., Maryland and Virginia with connections to espionage.
Walking the streets of D.C., Wallace said locations where spies lived, worked, held secret meetings and conducted dead drops are all around.
“I think it's about 100 percent certain that there is a spy site in your neighborhood, somewhere in your neighborhood,” he said. “I assure you, you can walk to it.”
