Thanks for some good news, Shawn and thanks WWF. I was in the Royal Chittiwan Park (another tiger refuge in the Terai in Nepal) and was quite impressed. Most (all?) of the guides were chosen from locals and trained, and attempts were made to connect people from the villages nearby to the park. (Didn't see any tigers, but a did see a leopard, thanks to my guide.)
