Dorothy writes: I have visited the Grand Canyon a few times in my life. It is a majestic wonder of the world. But on my Bucket List was something that un-nerved me: walking the Sky Walk at the Grand Canyon. You see, I’m not too crazy about heights. But between my love of the Canyon and my determination to live the best life I can as the years tick off, I did it! Glad I did too – the view was amazing. And a note to others who might be interested in doing this? Don’t look straight down. Just gaze out and you’ll be fine.
