Christopher was on time and very very knowledgeable. He made our day interesting and worry free. He tailored the tour to fit our interests and arranged our sites for our convenience. His ability to park his car and still meet us at the site in a short time not only saved us from doing a lot of walking but maximized the good use of our time. At one stop after another Christopher managed our visit so that we did not stand in long lines and we felt that we received special access again and again.
