452 Slow Train to Switzerland; Artist Safari; Joys of Travel

Learn how tourism as we know it was invented by middle-class, Victorian-era English travelers seeking a pleasure trip in the Swiss Alps. Then listen in as a painter describes how peering into the eyes of savanna wildlife on an "artist's safari" deepened his appreciation for Africa's creatures. And join us as we examine the emotional benefits of travel, which start even before you've left home — and last well after you return.
