Lan, thanks for the extensive book list BUT you now have me quite concerned about our trip to Tikal. I had these concerns but my husband has convinced me that we should go to Tikal rather than one of the major Belize sites (Caracol?). If we go "escorted" with someone like Chaa Creek are we not 99%+ safe?? When I hear concerns like this from someone in the tourism industry there, I'm listening!!!!!!!!
