I wouldn't do Branson due to the logistical issues associated with moving around (numerous) groups of cars. Springfield is a bit too far north/west of the good twisties. However, if there is somewhere around Beaver Lake or on the far side of Table Rock Lake from Branson, I think southern Missouri / northwest Arkansas would be great (assuming we can find the necessary lodging). It's centrally located and not overly far from a number of large metro areas. I used a 500 miles radius - the distance from home to Bushkill and the same distance I travel to go see my daughter (a full day, but not an exhaustingly full day). In that radius are - St. Louis, Kansas City, Dallas, Austin, Houston, Oklahoma City, Tulsa, Birmingham, Nashville, Memphis, Louisville, Indianapolis, New Orleans, the edge of Chicago, Little Rock, Springfields (several), Heber Springs (which is key), and many others. There are great twisties, great scenic drives, and numerous nearby attractions if you are inclined to get out and explore. And it's "home" for me. So if SolNut will get onboard and be eyes on the ground, AND we can get a couple more key people involved, then Karen (Twitchy) and I would be willing take take the point on seeing if this is a feasible location and, if so, running with it.
