The 90 minute spy tour was incredible. Ice history tour would have been a good alternative but I knew very little about the spies that shared nuclear bomb information during WWII. Nicknames of. David Greenglass and his wife were Bumblebee and Wasp. His sister in law was Ethel Rosenberg husband. A young unmarried popular spy.was scientist Klaus Fuchs, a . British communist. The $15 tour included entrance to both parts of the museum. The restored home on bathtub row was very interesting.
