We were a bit sluggish getting started today and ended up at the Shake Shack again for brunch. Once finished we caught an Uber to Arlington Cemetery. We are loving catching Ubers everywhere, you meet the most amazing people. We have had 4 female drivers in DC, one was a retired lady who'd had the most amazing career and was bored sitting at home so decided to Uber and was loving it. To say Arlington is huge is an understatement. Line upon line, row upon row of graves. The small white graves were those issued by the Government, the more elaborate graves were purchased by the families. They have between 20 to 30 burials a day, today there was 23. They are either burials of current or past veterans and we heard the gun shots from one of the burials. We visited John F Kennedy's grave site which I thought would be more elaborate but the interesting fact was his grave was placed in front of Arlington House one way and when you turned around there was a direct line to the Lincoln Memorial. It was an amazing site. We then went to the tomb of the lost solider. There are only 3 soldiers buried there. A moving tribute was carved in stone saying something like "they didn't know who they were, they were only known to God". There was one soldier from the first world war, one from the second world war and one from the Korean war. There was one soldier from the Vietnam war but they discovered who he was and moved him. The tomb was protected by guards 24/7, 365 days a week. They have a changing of the guard every 20 minutes I think. They walk 21 steps every couple of minutes. 21 is significant as it replicates the 21 gun salue which is the highest commendation a soldier can get. Each area of Arlington is segmented into regiments and the cemetery will run out of room by 2025. We then walked across memorial bridge to Lincoln Museum and tried to find the Smithsonians. We ended up at the Natural American History Museum which was great. We were hoping to go to more museums but ran out of time. 2 days in DC is just not enough. I love this place, I feel comfortable here and would definitely come again if I'm ever on the East Coast of America.
