The weekend we’ve been looking forward to for months: Daylight Savings! Also, known as a time parents dread because they have to get their child back on a sleep schedule, adapting to the time change. The weather should be warm and sunny on Saturday. A perfect time to take advantage of the free admission to Dumbarton Oaks 1703 32nd St NW, Washington, DC 20007. Between 2:00pm-5:00pm (Sunday as well) you can roam the gardens and run the long lawns.
