I got back last Friday from a week away in Washington and I fell in love with the place. I was there for work so didn't have too much time to get out and about. I did land on a Sunday though so had that day to myself to sightsee which was lovely. It's such a great city!
I just walked and walked and walked... One of highlights was chancing upon the White House Spring Garden Tour by complete accident. The timing was perfect as they only open the gardens for two weekends a year so I was able to go in and have a closer look. I didn't have time to see too much of the city but I loved walking through Georgetown and the National Mall and it was such beautiful Spring weather. It's definitely a city to revisit.
One of the best things about being in the US was the food. I love bagels and they are so hard to find in Singapore so I took advantage and had a bagel with cream cheese every morning. I also spent ages in Whole Foods :)
