I haven't been on any of the Grand Canyon trips while visiting Las Vegas, but sure would love to go on one some day.
My wife and I watched a show about how the Skywalk was made and it was pretty awesome how they built it.
A lot of man-hours and strict safety pre-cautions went into building the Grand Canyon Skywalk.
They really went over-kill with the safety on the Skywalk.
I forget how many fully loaded semi-trucks they mentioned could drive on the Skywalk, if they would fit.
Let's just say that you won't have to worry about it giving way even when it's packed with people.
I may be like a few of the people I saw walking "scared" while looking through the glass panes on the Skywalk, as my vertigo may be off slightly with the first glance at the ground some 4000 feet below.
