Roger,
Matt and Mark are right, Huron Valley, while a cool road, is just too busy to be much fun. When we did this run last time (right after Mark got his S/C installed) we had a blast, and I remember hitting triple digits on a few occasions at least (I got stuck behind a slowpoke. . . hehe, though he fixed things later by adding a Venom N2O setup. . . but I won't mention his name, lol)
Trust me, you guys will have fun. I'm kinda bummed I won't be able to make it.
