Adding to Marks comments, today at the Bicentennial center atheletes were denied bringing in even just bottled water. I witnessed a situation where security was called to the entrance for two men bringing back in coffee cups that they had purchased in the concessions and then absentmindedly ventured out into the entry commons area.
My point is that it is happening all over and even tighter then what the expo does. I bought $3 20oz bottles of water and diet coke today. Lets just get over it.
