A luxury apartment building opened in Houston. The rooftop pool has a section that hangs over the side, so it looks like you're standing about 300 feet above the ground with nothing under you. My wife Tracy would have an absolute heartache! She is afraid of heights, and can't even sit in the upper deck of the Xcel Energy Center without having a panic attack. It would be fun to bring her to this pool, and just not say anything until she swam out to edge.
