Since Nov 2002, every two year we fly to Washington, DC to participatein Twin Study hosted by National Institute of Mental Health. NIMH puts us up in a hotel, covers our food, and pays the boys a small stipend. We fit in a day or two of exploring the DC and Mall area and riding subways. The first year we went I was pregnant with Jenna, but in 2004, she was able to join us to explore the zoo and museums.
