FIX THE 48 ERRORS.. don't use table, use divs(google like divs better). Privacy Policy And Terms of Service is something we use to have in the footer, not in the sidebar!! Other than that, it looks pretty good.
dude, i think you should buy some professional photos at Corbis.com because yours look pale and simple (try adding some people smiling or looking happy, something that increases the attention of the users to stay checking your site and thinking about making a trip to DC or something like that). you also have the error on weather.
