It's in the genes, I guess

Back in 2005, the day I graduated from medical school, my entourage and I took a trip to the Carnegie Science Center. It was a fun day of wind tunnels, simulated earthquakes, and meteor rubbing. Noah was the only kid in the group, but we all frolicked. The most fun, however, was definitely had by my dad in the miniature train exhibit. It's a pretty cool exhibit, running 5 trains and a tram car with scale replicas of many famous and historical sights from Western PA. The lighting changes over the course of an hour or so to go from sunrise to sunset to sunrise again.
Some months later, when my dad visited again, one of the first things he asked for was to visit the trains again. We weren't able to because it was closed for renovation and I am sure that was the low point of his trip.
Today we took Nathan to the Science Center and learned that besides hand shape and broad shoulders he has something else in common with his Buff Grandpa. He LOVED the trains. From the moment we walked into the room, he was mesmerized. He tracked every train as it came and went with an enthusiastic flapping of legs and arms. It was genuine fun to watch him study the little lit up buildings and the glowing trains. Though this time I was the only one making "choo choo" noises, he kept up a constant babble of "bwah, bwah, bwah". He looked from track to mommy, to daddy with an incredulous, "are you seeing this?" look on his face.

My dad is coming to visit in a few weeks and I look forward to watching them enjoy the trains together.
