We continued our car theme trip to Bowling Green, KY., about an hour north of Nashville and home to the Corvette, one of the auto industry’s most iconic cars. Not only can you visit the manufacturing plant and watch Corvettes roll off the assembly line, but you can visit the National Corvette Museum. In addition to the amazing Corvettes, the museum is famous (infamous) for the sinkhole that swallowed up eight Corvettes. On the second anniversary of the sinkhole the museum is debuting a social exhibit: Corvette Cave-In: The Skydive Sinkhole Exhibit that details the cave-in to restoration attempts.
