The views were amazing and our tour guide Jim was great. This tour was very informational, creepy, and cool. I leaned so much history. This tour was the highlight of my trip!

Our guide James knew every person in our small group almost immediately and personalized the experience for everyone. Tons of firsthand knowledge from experience as a Capitol guide and living in DC his whole life. Told stories to teach facts with background and context as well as witty asides. Our group had folks from AZ, NC, KS, MO, Iran, Austria and China! Just a great experience!!

Thank you very much for Barney's company today. He is warm, friendly, kind and professional. We are very lucky to have such an excellent driver and guide. He gave us a great experience on the day trip to Washington. I hope to find him again when I have the chance to come to New York. Great!
