 Pentagon is the world's largest low-rise office building. Throughout the Pentagon, there are medical and dental facilities. There's a post office and a bank. We have gifts. On a typical day, I walk around five miles backwards. When I first started giving tours, I had one day where I tried to go down the wrong escalators about three times during the day. The ones that were coming up, I was trying to go down them backwards. My tour group just stood there and laughed at me. It definitely wasn't funny to me. It was really embarrassing to be going down the wrong escalators. We give around 5,000 tours per year, and that is around 100,000 people per year. To be chosen as a Pentagon tour guide, we first are chosen out of boot camp to go to our ceremonial guard units. From there, they do a long interview process with our chain of command to select us to come to the Pentagon tour program. When you first get here to become a public tour guide, you get 15 business days to learn 33 pages of information. Be able to walk the mile-and-a-half route backwards. Some of the weirdest questions I've gotten from tourists is probably where are the control rooms here in the Pentagon? Where are the secret tunnels? People think they're secret tunnels that lead from the Pentagon to the White House. Before I got into the Navy, I was a very shy individual. I still am shy right now, but when I am doing tours, I try to be as loud and outgoing and friendly as possible. I'll tell you guys a little bit more about the Outdoor Memorial. You guys notice I had really good cursive handwriting, so they made me write all this? Being a Pentagon tour guide definitely has helped me personally become more open, more approachable. My favorite part about giving tours is just being able to be here and be a spokesman for the Navy and just to become more confident speaking with the public.
