Have been to the Dragon 10 to 12 times and have yet to see it patroled by the police. I have seen a few acidents there with police and emergency present. On one trip we came around a corner and aparently an 18 wheeler was trying to negotiate a sharp curve (why he took 129 in an 18 wheeler I dont know) and because of his length crossed over the yellow line as a car was comming in the oposite direction - yep the car ended up under the 18 wheeler. When we got there they we trying to get the people out. One other time we got there just as a rider on a sport bike had gone over the side. He must have flow better than 50 feet in the air considering were he landed. A nurse was a corider on a bike that stopped just after us and she assistied him until the emergency folks got there. The interesting thing was I walked the area where he went off and there we no skid marks on the pavement only the dirt sholder. It apears he fixated straight ahead and not through the curve and went right where he was looking and almost never hit the brakes. Evidently it happens a lot.
We ride a lot in the mountians and as said many time at the Dragon. For what its worth the thing I believe are important are:
1) Ride your own ride and dont be intimidated by others (those with you or otherwise)
2) Keep your reves up especially on these v-twins, dont let the bike lug down shift this will allow you to pull the bike thrugh the turns.
3) Look through the turn, not straight ahead, not directlly in front of the bike keep your eyes several second ahead where possible. If your looking straight ahead thats were the bike is going to go (note example above), if your looking directly in front of the bike you will not be able to properly set up the curve and if there are any surprises (rocks, gravel, critter, etc.) you will not have time to evade.
4) Use as much of the lane as possible (left to right) to set up your curve with the least amount of arc possible and aim for exit point where you can see where the road goes after the curve (once you see this point is also the time that you accelerate the bike). Sometimes this happens very quickly especially at the dragon because as you come out of one curve you are immediatly setting up for the next.
Sorry for the long post. Hopes this helps.
