What lenses did you find the most and least useful in Washington DC.
I have a 17-55, 10-22 and a 70-200 2.8.
We will be there for 10 days and plan on seeing as much as possible.
Of course I'd like to bring at least two of them, but this is a vacation and not just a photo shoot.
Take all three if you can. If not then take the 10-22MM and the 17-55MM.
Be sure and visit the Air & Space Annex at Dulles AP. You will have a blast there with the 10-22MM! There is a B-29 (the Enola Gay), a Connie Tri-Tail, a Pan Am Clipper, a German Tri-Motor, a complete Space Shuttle (the Enterprise), a SR-71 (Blackbird) just to name a few. UWA heaven for sure
