Id recommend that you start early (5am ish). By noon there is an hour wait to climb the cables (see pics, it was just like that when we went). Nothing takes the wind out of your sails on a pretty day in the outdoors like standing in line!
"Nothing in this world can take the place of persistence. Talent will not; nothing is more common than unsuccessful people with talent. Genius will not; unrewarded genius is almost a proverb. Education will not; the world is full of educated derelicts. Persistence and determination alone are omnipotent. The slogan "press on" has solved and always will solve the problems of the human race."
