Jimi Hendrix [SEP] Military service
Before Hendrix was 19 years old, law authorities had twice caught him riding in stolen cars. Given a choice between prison or joining the Army, he chose the latter and enlisted on May 31, 1961. After completing eight weeks of basic training at Fort Ord, California, he was assigned to the 101st Airborne Division and stationed at Fort Campbell, Kentucky. He arrived on November 8, and soon afterward he wrote to his father: "There's nothing but physical training and harassment here for two weeks, then when you go to jump school ... you get hell. They work you to death, fussing and fighting." In his next letter home, Hendrix, who had left his guitar in Seattle at the home of his girlfriend Betty Jean Morgan, asked his father to send it to him as soon as possible, stating: "I really need it now." His father obliged and sent the red Silvertone Danelectro on which Hendrix had hand-painted the words "Betty Jean" to Fort Campbell.
