NYC is forcing me to learn the subway system

Ideally I can get from my house to the Brooklyn Children's Museum without transferring. That's if I knew what I was doing. Apparently the 2 and the 3 trains do not always run on the same path. Learned that the hard way. But I played it cool, I don't think my boys noticed. We got there, didn't we? And look at how much fun they are having at the aquatic station! Especially Owen. Nothing stops him from drinking 8 glasses of water per day.
