Hola, I am actually German, but living in Guatemala working on archeological sites (in the area of Tikal) and organizing scientific tours to ruins, where normally turists can't go. Also during dry-season real expeditions into the deep rainforest to visit very remote sites or to find new ones. Who is interested in Mayan science should have a look onto www.yaxha.de or www.cafeyaxha.com Saludos, Dieter
