Rte 40 from Oakhurst California to 120 west

I assume you mean Route 49? And yes, it's a good road but weren't you also the one posting on other topics about grades and curves? Highway 49 has some grades and curves, especially the part between 132 and 120. Everybody was telling you before to go from Yosemite on 120 to go down to 99 and take it north to Tahoe. The section of road you would have avoided by doing that is just as bad as the section of road you will hit on 49 going to 120.
