Gravelly Point is my new favorite place to visit in DC. It's a park just a few hundred yards from DCA's runway, so you can see planes take off/land closer than I imagine you could anywhere else. It's pretty awesome.
I've gone three times in the last two weeks, and managed to take a few photos...
"Hey Molly, how excited are you to be at Gravelly Point?"
Very ill-timed jumping photo
An awkward-angled/jumping/trying-to-get-the-airplane-in-the-picture, too photo. Doesn't Dave look super tall?
We finally got the plane in one...but I was laughing too hard
