Our guide, Tom Schultz, was a navy veteran with 20 years of active service. As such, he could answer all of the questions my son had with regards to military tradition, history and up-to-date explanation on military technology. As can be imagined, my son was thrilled, excited and focused throughout five hour tour - which would not have been the case had we visited the sites on our own. We visited Marine Corps memorial, Arlington National Cemetery, Navy Yard and Navy Museum. At Arlington we had a chance to watch changing of guards, which was quite impressive and even encountered a full honor funeral. Navy museum was small but very informative, exhibits encompassing almost all of the wars US navy has fought to date. We had an opportunity to eat with servicemen and visit official uniform shop. It was certainly very authentic and memorable tour. Would highly recommend it to families with boys or military history buffs.
