The tape can be found in Harpers Ferry, on a rooftop table of house #402.
Jesus Sunday: When my brother JD & I answered the call to head into Harpers Ferry, we expected to find an organized Free States stronghold. Now that we're here, it's obvious that no one knows what the hell they're doing. The other Free States families are wasting precious resources trying to restore Harpers Ferry and create a safe haven for survivors. Instead, they should be turning the town into a fort and stockpiling supplies to prep for the long haul. We'll still pitch in, but we don't plan on sticking around long to see what happens. We don't think that Harpers Ferry will ever be safe, so we're going to use our share of the supplies to reinforce the bunker at our cabin.
