First knock and our discussion

This was recorded at 10:30 at night in a remote area of Tennessee in 2007.  The above whispers were only the beginning of this encounter.  Nathan picked up eye-shine, and we could hear rustling in the darkness around us.  On this clip, we discuss the whispers we had heard and the eye shine we see.  When it quieted down, Nathan gave a single tree knock and we waited for some response.  There is a loud crack that is something hitting the truck, I ask if it was him, he says 'No', I say I am ready to leave, he agrees, and we both jump into the truck which Judy starts driving away without lights on.  You can hear the volume of this impact in this clip.  The truck does not have a single mark on it anywhere from it.
