Like most of my memberships, this one has been pulled out rarely, once to use the bathroom during the Star-Spangled Spectacular and that's pretty much it. I mean, that place is for kids, and I only know one of those, and she's barely old enough to hold her head up by herself, much less care about dinosaurs and spaceships. But then the ladyfriend remembered it was there and we were members, so we headed down for a field trip with prepaid admission. As we walked in, I remembered what I know about the way this place got here on this particular corner, and that it's more than just a place to learn about science; it's everything that's dangerous about development as social control, and just because we've largely forgotten that history doesn't mean it's not still relevant. The questions that animated the redevelopment of the Inner Harbor in the '70s and '80s are still here, as we figure out where to put our parking lots and public housing and transit lines. But the Maryland Science Center isn't just that history. It's also a place to learn about science, and, on this sunny Saturday, a place to look at the sun without burning your eyeballs right out of your skull.
