We spent six hours at the Maryland Science Center, part of it with Dave (who played hooky for a few hours). What a great place for curious people! Lots of cool hands-on stuff about so many topics. We went from paleontology to astronomy to geography to medicine....
And the next day was the National Aquarium, probably the one absolute must-see in the Inner Harbor. It was World Oceans Day when we went, which meant extra exhibits and activities (and prizes). 
We splurged on the dolphin show, which was worth it. Two of their dolphins had calved this spring, and we got to see the moms and calves. I thought it was funny the main trainer was pregnant!
The other highlight of Baltimore was Fort McHenry, which we saw with Dave. Katie and I had read a children's book about the woman who made the big flag, so it was neat to drive by her house downtown and then see the fort. Katie really likes the national anthem, so the exhibits were fairly interesting. Dave and I caught her singing it around the house this week.
The vacation part of the trip for all of us was a visit with our great friends Ingrid, Jeff, and Emma in New Jersey. 
Emma invited Katie to her dance recital, so we all tagged along. LOTS of dancing - Emma was in 10 numbers all day, four in the one show we saw (one of five different shows all day long). What an incredible undertaking for the dance school. But Emma was great, and Katie loved the dancing - sat upright and mesmerized, even after being sick most of the day. And we all got rewarded with fabulous Indian food. Oh, and mehndi painting (henna) for the girls. 
After the week, I think we'll be piecing together a "vacation" of short visits and travels - to fun places and of course to great friends.
