I'm leaving in a few days for a spring break trip with the family to the northeast (US) -- I've already covered Boston and NYC in previous posts. I'm looking for suggestions of attractions and events that might lead to interesting photo opportunities. The trip isn't primarily a photo excursion (I probably won't be bringing a tripod), but I'd love to come away with some frame-able images to remember the trip by. I'm traveling with my wife and two kids (aged 9 & 10). We'll be in Washington for four nights in mid-April (17-21). We're staying near Gallaudet/NoMa. We're planning on hitting all the highlights on the National Mall as well as visiting some of the museums. The Museum of American History is at the top of our list. We may bypass the Air & Space Museum since we feel we've done aviation museums elsewhere and the kids don't have a keen interest in the subject. We'll also likely avoid the Natural History Museum since we plan to attend the one in NYC. We've got tours of the White House and Capitol lined up. What are your favorite photo vantage points around the city to get images that capture the essence of the place? Any particularly good places to people watch? It seems that we might catch at least the tail end of the cherry blossoms. I'm also open to any restaurant suggestions you care to share. Beyond Ben's Chili Bowl what are the iconic D.C. staples? Any "secret" local knowledge you care to share is greatly appreciated.
