Very good black and white. Great contrast and sharpness. Back in the 80's I lived in Chantilly and then Centreville and made the commute down 50 or 66 to Tyson's Corner for 6 years and then downtown DC for another 2 before I left. I was out to the falls a bunch of times, but I'd gotten away from photography during those years so didn't take a lot of pictures.
Excellent shot.
