Just past ukiah, it stays the type of freeway you are on pretty much, then it starts to climb uphill a bit towards Willits. You will most likely drop to 45-40mph, until you reach the summit. Then it's a long straight drop into Willits. 101 proceeds through Willits, and then becomes a mix of easy highway & light twistys through the redwoods. IF you were ok with 101 to Ukiah I think you will be fine. PM me for any detailed Q&A m.
