That road is great! I mentioned it before, I always go over it when I can. People slide down it on sleds in the winter when its closed for winter traffic.
Another good one is Route 108 in Smugglers Notch, its a true 1 lane wide road with 2 way traffic in spots. For some turns I am in 1st gear. Here: Google Maps
I’m a big fan of 151 and 150. If you take I-90 to exit 10 (Miller Rd) and take a left off the exit, it’s 30 mph for a big through the residential but it eventually opens up to 55mph and you’ll also eventually see signs for 151. Minimal straights, not usually a whole lot of traffic. Oh, and 66 is a pretty good one too. It goes from Troy into Sand Lake. (and I’m sure past it but I’ve never been that far on it)
I was just on 66 coming back from from jiminy peak last night, it was unfamiliar and dark and I was driving my Cadillac but it was a fun road. Some lady in a Luxus SUV let me pass at one point.
