Mitchel and Bonnie left Narrowsburg, NY on July 27, 1973. They had planned to hitchhike to Watkins Glen, NY to see Summer Jam. Summer Jam was a concert that featured The Allman Brothers Band, The Grateful Dead and The Band. It is estimated that between 600,000 and 800,000 people attended the show. The two teens never made it back home to Brooklyn. Did they even make it to the concert?
