Dean,
You know better than that! My best time last year was a good 8 seconds slower than yours and I have been concentrating on the coupe for the last year or so and I haven't made any changes to my Cobra. But, I plan on having fun!
Bill just bring the ole credit card and give it to Sharon at Registration (the Highway Patol won't bother you at Gateway) and she will get you all checked in and ready to go.
I really do hope you can make it you are a very good driver and some of us like to use your times for our benchmark.
