Grand Canyon

Have you ever been to the Grand Canyon?  I have seen it from an airplane on the way down to Tucson in 2005, but I've never been there.  I think it would be gorgeous to see. I wonder how small you would feel when you're standing next to the edge of a plateau.  I really want to visit the Grand Canyon this year, but haven't scheduled it into my calendar just yet.  I'm thinking of starting a list of things I want to do and see before I'm 30 and add this to my list.  What do you think?
