I thought this interview with Mitch Payton was very interesting. I'm not sure this is a real possibility, but what if?? Click on the blue link and listen to the first 15 minutes specifically between 9 and 13 minutes. You don't gotta listen to the whole thing, but the first few minutes will make you think. http://www.racerxonline.com/article/podcast-mitch-payton.aspx
