It is crazy there. You drive down the tunnel and when you come out its like your in another world. You have to do Half Dome, its an all day hike there an back. It is so worth it. While your there swing over to Sequia National Park. Words can not do those trees justice! There are 3 of them just before you get to SNP that will blow your mind. My avatar is from right about here I think. https://maps.google.com/maps?q=37.725872,-119.600764&hl=en&num=1&t=h&z=17
