Who says the economic news is all bad? I prefer to look on the bright side. A weak economy means that even the priciest of adventure travel companies are offering more discounts than you can shake a hiking stick at. Here are 100 of the best discounted trips in 2009 from some of the world’s top adventure outfitters.
