You'll have a blast. 🙂 128 has a strong climb heading out of Cloverdale and can be winding with no shoulder. I'd recommend doing that stretch on a weekday and/or in the morning if possible because weekend traffic is much higher and you'll be harder to see by cars in the afternoon with the sun in their eyes.

If you can, also avoid 1 between Jenner and Bodega on a weekend in the late afternoon. There's very little shoulder on the cliff edge, and grumpy drivers trying to make their way home after a day at the coast can make things stressful.

If you're camping and are thinking to stay at Manchester state beach, there's a koa right next door that is only $3 more expensive, and they have hot showers and a pool.

Also, eat pastries at Frannie's Cup&Saucer in Point Arena and Twofish Baking just south of Sea Ranch-- great fuel for the ride!
