night practice in the city

My goal was to have some shots of the city at night, maybe a couple streets and buildings, but then a jazz band was playing on the street at Dupont Circle and I got hooked in :) Below are some of the better ones, but I had a rough time with this set of photos. Everyone was moving and dancing, which was absolutely great, but that led to a heck of a lot of blurry photos. Some of the blur is cool though, like the motion on the washboard, but not all of it works. This was my first time shooting with sodium vapor street lights too -- and now I know what people mean when they say the flare (light spots) comes out green. I have to read up a little more and try this again sometime. I know motion at night is hard to capture though -- everything I've read about night photography so far talks about a tripod and keeping things still. I can't help it if the world likes to move at night too :) Even though the photos weren't my best, I still had a great time out on the street.
