"Haven't they got anything better to do?" is the ironic subtitle of this encounter between a group of very different travel writers. Travel stories from the USA are recounted by Jo and Gareth Morgan ('Backblocks America'); bicycling in South America in Eleanor Meecham's 'Llamas & Empanadas'; and travelling in Tibet in Ian Robinson's alarmingly-titled 'You Must Die Once'. TV cameraman Geoff Mackley chases bad weather all over the world in 'Extreme Danger' and Pico Iyer reflects on the relationship between travel and globalisation in 'Sun after Dark'. Graham Reid controls this international traffic in a busy and entertaining session.
