Richard, you have a great idea here and many have even made some good suggestions. Personally I think you guys should talk to Wayne Turpin an make this a part of Run & Gun. They could make a special class for manufacturers to compete in. After all this event gets good coverage in the Mags and it can only bring more attention to our National event. Work out the formats and send out an invite to all manufacturers. They have good people at the run and gun who do a good job at tech inspection. All you need to do is set it up with the proper guide lines and I bet you will get a lot more participation from the manufacturers. Also it's centrally located which makes it good for all in the travel aspect.
I was impressed at how well R&G was run. They really went out of their way to make it a safe and fun event. The track is a good one too. It may not be a willow or a Road America but it does the job well....Think it over, I think you'll be surpised.
