>I went to the 86th floor balcony of the Empire State building once<
I have to hold onto the shoulder of a perfect stranger going down the open stairwell of a parking garage (from the second floor!). You should have seen me going up the Space Needle the first time, plastered to the back of the elevator. But the second time I went up it was a breeze!
Stepping onto that glass is just freaky until you get used to it. Then you can mess with the newbies.
