Jim,
Are you gonna take 199 at Grants Pass?
If so, there's a number of places to stop...
You could cut across to 101 at the Hiouchi Bridge and head north just a tad... That would get you to either to Harris Beach in Brookings or Ludlum upstream a ways on the north side of the Winchuck River.
If you stay on 199 there's either Stout Grove or Jed Smith before you get to Crescent City. After Crescent City on 101 there's Mill Creek just up the hill outta C.C., or Prairie Creek, or Patricks Point. Take the Newton B. Drury Scenic Parkway for Prairie Creek, in fact... Take that road regardless while on 101. It will save you going up over a mountain on the new road and save you some time too. (That road is actually just the old highway)
Patricks Point is gonna put you about four hours outta Mendocino.
Oh and when you get off 101 to head over to the coast, I'd reccommend you cut over at Legget. You can either cut across around Redway to get to Highway 1 at Fort Brag or go down to 20 just North of Ukiah to get to 1, but the road at Legget is the quickest to Mendo coming from 101 north.
The road at Legget is windey, but the road at Redway is windier. I don't know how windey the road is at 20, but it's gonna put you south of Mendo and will add quite a bit of time to the trip.... That road is good for folks coming from the south unless you take I-5 all the way to 20 at Williams.
So what ovens are you bringing???
Got the 22 and the Elk seasoned up yesterday and threw a second coat on the 20 that Shelly brought to me at Shasta. I'll be bringing that one for the prime rib... Unless you wanna bring your 20 and have me break it in for yaa.
Oh Hey!!! If you take 199 down, stop at Taylors in Cave Junction (Right across from the DQ) and enjoy the worlds best polish sausage!
You know... You could also pick me up one or two 5 lb. bags of Smoked Beef Polish. (Skinned if they got it, skinnless if not)
