I have attached some great links here that are part of the Minis on the Dragon (MOTD) national event in the Spring. One gives great advice about driving the Dragon or any mountain road. This one is authored by Jack Roland (MINIBee) from Florida who will be joining us for MSSD (he is a welcome regular driver in the Fall). There is a great video at the bottom of the page. It is full of good advice but the FRS channel he mentions is for the MOTD event. We, as a club, always use 20 sub 20.
The second like describes, maps, and even has illustrations of some of the best roads near Fontana Village. This is another well made webpage from MOTD.
