Chris Christensen had the foresight to start a travel podcast before almost anyone had even heard of podcasts - way back in 2005. The Amateur Traveler podcast is still going strong - and is approaching its one thousandth episode.
Chris and I chatted about the evolution of podcasting in general and the Amateur Traveler specifically, his approach to life now that he has retired from his 'day job' to the podcast, and what he thinks it means to be a thoughtful traveller.
