My kids and I are driving from San Francisco to Las Vegas this weekend but would like to drive through Yosemite (probably no time for more than a couple of quick stops) for the scenic view. I'm thinking of taking 120 to Lee Vining, CA then south to Vegas. I realize it will be about a 13-hour trip but there is absolutely no possibility of staying in/near Yosemite due to time constraints. So I would appreciate your feedback on the following:
1) Is 120 the best option for this trip or can anyone recommend a more attractive route?
2) I have never driven through Yosemite before, so how dangerous is the drive? I ask because I may need my 18-year-old son to help with the driving.
3) What would be the highest elevation?
Thanks in advance for your input.
