The 38 is fine. It's old and twisty. The 18 is basically a highway. Cars are doing 50+, both up and down-- and there's a lot of 'em.
Most times I head to Forest Falls, I might see one or two cars past the 38 cutoff. The lower 38 (below the cutoff) is freshly paved, and in most places the shoulder is 4+ feet.
