Where In The World Is Ln?

I visited (broke into) Buzludzha last summer. I tell you some history and my adventure of the giant meeting place-- but then... I become stumped as this weird sound shows up in the recording...... What is it? Not really sure....   www.LNLurie.comLN.Lurie@yahoo.com   Thanks to Chris Allen for editing. Dan, Nick and Matt for being my adventure buddies. and the Bulgarian Communists- for abandoning the coolest building I've ever been in!
