Hi i am holidaying in las vegas in january and are going to drive from las vegas to yosemite though to san francisco we are traveling fom australia and this will be the first time driving in america i have planned a one night stopover in yosemite but after reading forums etc, am a little concerned about the distance, road conditions etc, any advice would be much appreciated the whole idea was to see the beauty of yosemite and snow but maybe there are many lovely things to see anyway along another route thanks!
