This is one of my favorite attractions at the science center. I am amazed at the amount of care and detail that goes into each design of the structures. There's so much to see that one visit isn't quite enough. Most recently I had the best visit.
One of the volunteers, Bob "Tink" gave my friend and I a personal tour of the exhibit. It was so very cool. Bob knew sooooooo much about the exhibit, history of each of the modeled structures and added his own personal experiences including showing us pictures of he and his wife visiting the inspirations of the models. Wow. This made the exhibit that much more interesting. It's kinda like have great service at a restaurant. The food tastes better when it's delivered with care as the trains seemed to really take life with their conductor showing the way. And, speaking of taking life...I was there early enough to watch them come to life as they were turning on the exhibit as I entered. It was really like A Night At The Museum experience. Fun!
Not only is the exhibit impressive with its artistry, but the investment of the volunteers is priceless. Go see this!!
