“In those years before mobile phones, email and Skype, travelers depended on the rudimentary communications system known as the postcard. Other methods--the long-distance phone call, the telegram--were marked "For Emergency Use Only." So my parents waved me off into the unknown, and their news bulletins about me would have been restricted to "Yes, he's arrived safely,"and "Last time we heard he was in Oregon," and "We expect him back in a few weeks." I'm not saying this was necessarily better, let alone more character-forming; just that in my case it probably helped not to have my parents a button's touch away, spilling out anxieties and long-range weather forecasts, warning me against floods, epidemics and psychos who preyed on backpackers.”
