I'm liking August 28-29 mention simply for the location: Mid America Motorplex is practically in my backyard as far as regional tracks go, plus it was designed by Gingerman Raceway's designer. MAM is great, but painfully flat, so I still prefer Gingerman. Sitting on Gingerman's hill and being able to see the entire track is a beautiful thing - especially when they were running Viper-Ferrari Wars.
CJ, I don't know anyone in SVTOA, although I'm somewhat ashamed to say that I'm not a member. If you want to start digging around for interest on that end, that would be great. I think SVTOA's involvement for a track day would be beneficial, especially for overall turnout. Since Frank is in SVTOA, maybe he would have some valuable input with that idea. I do have some connections with the Mustang Club of Central Iowa and the Northwoods Shelby Club, so I'll see what I can dig up.
