Last week I had the pleasure of interviewing Andy DeHart, a shark expert who currently works at the National Aquarium in Washington, D.C. Dehart talked to me about his first experience with sharks (when he was five!), about his interest in conservation of the species, and about Shark Week, Discovery's annual documentary series (in its 21st year this summer). Other than Big Brother, Shark Week is the only reason I turn on the TV in the summer. I was pretty excited to talk to him about this year's event.
