Micaela's and Christian's US connections enhanced conversations and helped relieve our concerns about being stereotypically arrogant Americans while asking possibly sensitive questions. Having a "zoner" guide also added a lot of social and historical insight. Sendero Panama always focused on what interested us and really knew the answers. If they didn't know, they didn't make up an answer. They had all of the details of our several tours under total control. Our tours were Ancient & Modern, Barro Colorado, El Valle de Anton, RR to Colon and an Embera village, and the Canal Zone & museum.
