It is totally amazing to me that most of the posts on this forum are about driving a car quickly acros the terrain in an efficient manner to see all the "Big" sights, and then be gone. Have we all forgotten that this is a national park that is huge that to really see and know it requires the use of our feet on the ground, and a bit of effort and time.
Oh, you have driven through Death Valley, now you can add it to your list, "Ive done it" "I've seen it" really? Really?
Do we remember the word "Explore"? Aren't the parks supposed to slow us down? Breathe? See? Smell? Touch? Sweat? Walk?
