We are headed for Yosemite after Easter in the Bay Area. We will be spending the night somewhere near Modesto/Manteca and then heading into the park for a couple days. Which is the recommended route to the valley, Hwy 120 or Hwy 140? I am interested in which would be the shortest time wise and which would be the best to avoid car sickness (not as many curves). Any help would be appreicated.
