Wow, and how fast were you still moving, lowest gear I have ever needed was 3rd, on my 5 speed, traffic was down to about 40.
Down west slope of Newfound Gap in Smoky Mountains National Park. Speed limit was 35mph, many hairpin turns with 20mph speed limit.
The Dragon's Tail just south of the park is similar but not as steep.
Not talking Interstate Highway travel here!
Think I was up to 30mph at 5000 rpm in first gear.
