On the way to Baltimore to got to the America Visionary Art Museum, we stopped by the NSA. We didn't see if we could drive up to the main building (see below photo), but we took the winding path to the closed-for-the-day Cryptology Museum. I checked my cell to see if it was being tapped. And sure enough, it was! No, not really. Actually the battery was dead... but why??? Dum Da Dummmm!
