All the times I had visited DC I had never been to the US National Arboretum. It is known as a must see in DC. It is a large park, but what really caught my eye were the columns that stood alone away from it all.
I hope you enjoy them as much as I did. Especially since I had to wait a good 20 minutes for everyone to walk away. My husband was getting quite antsy since it was really HOT!
