I must have missed the part in the article where it describes her as wearing spiked heels.
You are wrong on this point. There are major structural faults at work in order for a publicly accessible walking surface to not be able to handle a 300 or even a 400 pound human of either gender wearing any kind of shoes. Yes it's a funny story, and normally I let comments go that I disagree with. I don't know why, but I just had to jump in on this one.
Freedom of speech, have at it. :)
