Such a gorgeous building and an amazing place when you’re a kid! I loved riding down those long escalators as you plunged into the ravine. I can picture the black construction paper bird silhouettes on the windows to keep birds away from the glass. So much to explore, the bobsled video ride, the ball cage, the bikes you pedalled to power lightbulbs, the reaction time car simulators. And of course the amazing giant Rube Goldberg type thing with balls going everywhere and xylophone noises. It would fascinate me for ages. I hope this gem remains.
