Good read.
I live about 1h from it but do not feel the need to attempt it. There are a handful of roads in my vicinity where I can have fun and I truly also do not fully trust my driving skills, even with a few track sessions in years past and karting every couple months. I roared my way 90-100km/h around 40km/h hairpins in WV this past weekend and that is a good shot of adrenaline and fun but one at a relatively crowded road like the Dragon, a slipup can be catastrophic.
It is why I ride DH mountain biking. I get a greater sensation of speed and even higher risk going over jumps and drops and boulders at speed, but at least if I wreck, I haven't done anything illegal and don't need to deal with insurance. Well, maybe health insurance, but not car insurance
