Been there, done that! Spectacular scenery. My stirrups were one notch too short. By the time we got to Phantom Ranch, the blisters I had on each butt-cheek had burst. Then I got to ride back up the next morning . . . . Still, I'd do it again in a heartbeat.
“We should be careful to get out of an experience only the wisdom that is in it and stop there lest we be like the cat that sits down on a hot stove lid. She will never sit down on a hot stove lid again and that is well but also she will never sit down on a cold one anymore.” - Mark Twain
