good guys to go with.....
going to Central America this winter sounds awesome. Especially while I am battling the cold and darkness of winter in Alaska. Anyways, in Costar Rica, go with Green Frog Adventures in Turrialba. A couple of Local guys from Colorado run the show and have been doing it for almost 10 years down there. They really know their shit. Kirk Bohem or Travis Lloyd are the names of the owners, on Yahoo, just type in 'greenfrodadventures.com'. They cater to anyone and specialize in custom itineraries.
As far as Honduras, I went down there to work as a guide a few years ago. Rios Honduras is a bigger company and definately has higher prices. The guy I worked for was local, knowledgable and cheap. His mane is Jorge Salaverri and he owns La Moskitia Ecoaventuras in La Ceiba. He is a great guy, very nice and personable. Check them both out, and tell them Tyler from Alaska sent you, might get you a discount or something(?). Have fun.
