I had a bizarre dream last night about this disaster. I had pulled up to the museum in the ZR-1 for the Gathering, and there was a huge blinking neon sign on top, "Corvette Caverns".
Inside, they had partially filled the hole and installed a spiral staircase in the rotunda, leading down into a natural cavern. There were numerous exhibits, and cars were displayed on the cavern floor. "Big Block Grotto", with a light show and a recording of an uncapped L88 blasting through speakers. It was amazing, but cheezy, and way too touristy.
What a great idea!..............Naaaaaaaaah.
