Tentatively thinking about a So. Cal. trip this summer - DL (a MUST), Hollywood, drive to Yosemite, over to San Fran and down the coast. I get pretty car sick on twisty, turny roads. I'm reading everyone say that the coastal road is just that. Will I be risking car sickness here? Also, what about road from LA to Yosemite - should we travel shortest route? Is that up the middle/valley? Any twisty/turny roads here? Thanks!
