Guys, FWIW...the police have become increasingly tough on speed on the TOTD as well as on some of the near by drives....particularly on the TN side. I was up yesterday and they are really holding people to the 30 mph speed limit. People were being pulled over for 5-10mph above speed limit. Some got warnings others got tickets....and they were pricey ($175).
Just be aware that on the Dragon it is more heavily patrolled with both police bikes and cars, so be very watchful. Other drives like the Cherohalla are still OK and Rt28 in NC was good too. They have reduced speed limits on a number of the tributary back roads so be mindful.
