The Medford Public Library is co-sponsoring “Going to Extremes,” an online presentation by adventure travel journalist Peter Mandel. Follow Mandel as he hunts his stories and photos in the world’s far corners, including Antarctica, India, Egypt, Patagonia, the fjords of Norway, the mountain pathways of Japan, and the deserts of Africa. He’ll show slides of his most extreme travel experiences — surviving a coup in Ecuador, visiting a “city” of penguins at the South Pole, fishing for piranha on Brazil’s Rio Negro, floating in the Goodyear Blimp, sailing on an Arctic icebreaker, camping in the African bush, and kayaking to the Statue of Liberty — and talk about how adventure travel turns to prose in today’s media.
