Last weekend my son and I did the "Rally for the Lane"
http://www.lanemotormuseum.org/events/rally-for-the-lane
I got the last slot for the October event. The car we had was a 2001 MGF with a convertible top. We kept it up since the weather wasn't great.
Our turn around point was the Corvette Museum in Bowling Green. It was damp on the drive up and rain showers on the way back. There were two cars that didn't have tops at all. One was a Renault Spider that had a tack but no speedometer. I'm sure that made the instructions more challenging, no ODO to gauge when to turn. Our car had a speedo in kilometers.
The Corvette Museum has a display of the cars that were eaten by the sinkhole. One car had only minor damage and was started after is was recovered from the pit. All the other cars are in their as recovered condition.
In the Lane Motor Museum there is a Lotus 7 ('67 I think) on display. As a bonus, after returning from the rally there was a reception in the warehouse where cars are stored when not on display. They have 2 Caterhams along with a lot of interesting (obscure, odd, "say what?") cars.
I would recommend doing the rally, you get to drive a car from the museum which will be something most of us would never get a chance to drive.
