Midwest storms are a sight to behold, but southern storms can be rather awe inspiring as well, especially when they arouse you from a deep sleep because the thunder is so loud it sounds like bombs going off and the lightning appears to be right outside your window.

While in Chicago try to see any of the museums. My personal favorite is The Museum of Science and Insdustry but maybe because I worked there for four years. But the Field Museum, The Shed Aquarium, and the Art Museum are just a worthwhile but the kids will probably like Science and Industry more. There is so much to do and they also have an Imax Theatre with some really amazing shows. All the museums have a free day, I use to know them all but a little search on line and you should be able to find that info before you go.
Too bad your going in winter there are a lot of cool outdoor things to do at the lake and around town in the summer.

When in DC, again I recommend the museums, and again I worked there. I would also recommend any of the monument tours if your into history, DC has a lot of it. Also try to get to Arlington if you can.

Never been to New York so can’t wait to hear all about it. One day I would like to go and spend a week or so there so take good notes.
