In Shanghai this week for work and went up in the tower with its glass floor. I am not a svelte guy, so everyone would scramble off the pane of glass I was on. You'd think a glass floor wouldn't be that hard to walk on, there are a fair amount of scratches and dirt on it so you can see it. There just is something to stepping out there messes with your head. My buddy couldn't do it. Little kids seem to have no issue.
Thanks for the comments. I'm just glad that I could find something this week. Shanghai is a great city and I had a great time there this week. This was the only scary part!
