My wife and I are driving to the Grand Canyon, South Rim, from Las Vegas in early February. We want to drive a scenic route over a few days from there (Grand Canyon, South Rim) to San Francisco and we think it may be nice to go through Yosemite Park, via Reno. Does that make sense to do this during winter weather, and what is the most scenic route to take? Any guidance would be appreciated. We have 7 days to get from Las Vegas to San Francisco.
