One of the only things I enjoy about taking the subway these days is seeing the defaced ads on the L train. Whether it's random chance, high schoolers or street artists the result is always good.
where I walk with my dog near my apartment, is also the remains of what was Fort Putnam in the late 1700’s and later Fort Washington near the Navy Yard. Not the largest park but a regular part of my routine and big enough to feel like you’re still out of the city when you’re in the middle of it.
