one ,more thing I need to mention all that have never been to the dragon before should keep their traction control on at all times,we have lost a few in the past coming up the dragon for the first time,and stay in your lane never cross the yellow lines,if you have someone following closely ,there are pull outs, pull over and let them go and give him a good wave,remember drive at your own speed never get out of your comfort zone ,okay be safe coming in, See at the dragon
