(john's voice in his head): I exactly remember what happened on June 12 2016...it was approximately 4:13PM...(BOOOOOOOMM)the explosion set off on Cahuenga peak next to the Griffith observatory....i remember i heard the explosion go off..around 2 minutes later...the nuclear siren was alarmed..strange..the nuclear siren was retired in 1992, which is a confusing question to answer
