We will be visiting with friends in Santa Rosa for about 3 weeks this coming March. Since this will probably be the only California trip I will ever have I want to do as much as possible. I see Yosemite National Park is about a 4 hour drive away. Would it be possible to be able to drive through the park in the middle of March? I've seen some videos and I know there is activities such as skiing--however all I want to be able to do is just drive, see some scenery and be able to say I've been to Yosemite. Can anyone give me some insight as to this being possible? If so,how should we prepare? I'm assuming winter clothes is a must--even just staying in the car (we are coming from Michigan so bringing our winter duds wouldn't be all that hard) but any other information would be greatly appreciated. Any thoughts about this being possible or is it just plain nuts??
