How to take a walking tour around a city while you are on vacation but not look like a tourist? Bring along your iPod and headphones and let the Audissey audio walking tours lead you around. Downloadable tours are currently available for a handful of American cities including Chicago, New Orleans and Miami’s South Beach. Tours are presented by real locals, though a few of the sound more like unreal stereotypes of locals — click through to the Audissey website and give a listen for yourself. The Ausissey tours do include some tidbits not found in the old fashion tree-killing guidebook, offered at a mere $10 per download.
