Forbes Traveler has an interesting piece about adventure abroad. There are details about seeing parts of the globe on the backs of burros, elephants, camels and other beasts of burden. Even African Serengeti tours from horse back.
While that sounds very exciting, I've seen lions take down zebras. Zebras are basically just cool looking horses. What if you bump into a hungry pride of lions and they decide to have a go? Could be trouble. And by "trouble" I mean grisly death. On the other hand, viewing of the video footage on YouTube could rival The Battle at Kruger. That's a coin flip scenario.
There should be elephant tours through Manhattan. What better way to see the concrete jungle? Way better than those double decker buses. Someone needs to get on that.
