Meh, 28 is pretty so-so, as is the highlighted part of 219 here.
The best part of this route is 50, and he does have highlighted some of the goodies.
Decent route, that could be made better, but if you prefer the main two lanes, like this person does, you won't be dissapointed.
Challenging corners, some good straights, wonderful scenery, keep an eye on gas gauge! Few peg scrapers, and...deer!
