I hope to write a landmark book covering more than 250 runs in Chiapas, Belize, Guatemala, El Salvador, and Honduras, most of which have never been described in any guidebook. Of course it would include a lot of things missing on this site, for example:
About the author. American-born Greg Schwendinger has been paddling Central America and the world since 1999 and has lived in Guatemala since 2002. In his previous life he was an electrical engineer for Intel Corporation in California. His passion is exploring new rivers and letting others know about them. He has survived more than 200 first descents in Central America. He has given slideshow presentations to paddlers groups and the Guatemalan Institute of Tourism, and written for Paddler magazine.
