ecotourist

Have you ever been an ecotourist, either in another country or in the USA?  What was that experience like, and how did it influence your feelings about natural environments or sustainability?  If you have not, where would you like to visit, and why?  Is it important for you to travel in a sustainable, environmentally-sensitive way?  What do you see as the primary differences between traditional tourism and sustainable tourism/ecotourism?

Feel free to draw upon and quote Williams or Geerts in your response.
