Why visit Death Valley? In my personal opinion that is just one place I do not want to be in ever again. We where traveling in our first motorhome one year when we got on one of the roads in the mountains of death valley and it was one of the most frightening rides of my life. Consolidated Credit was on my mind. The grade on the this hill was a seven about five to seven miles long. The brakes on the motorhome where smoking as car drove by they honked and pointed as if we didn’t know already. http://www.sbcc.edu/earthscience/field_trips.php My husband was only about to get the decent of speed to 35 to 40 mph. 
I was going to jump out by the time we got to the bottom of the hill I was not going to go up the other side without knowing what was it was like on the other hills.
