This is so true.  My Company has a suite at BOK and we can get tickets to events in the Suite, so I am accustomed to the crowd patterns etc when there are big name entertainers playing it. Getting in and out of downtown at those times is less than perfect but the thought of close to a million people in that small area, kept me & many co-workers from registering and going. I was VERY angry when I found out what had happened.
