I don't have a hat, I want one like those they were wearing for Taste of Chicago. I don't care much for the T-shirts,but I do keep my water at hand. Several folk that come to my office that run marathons (Disney,San Diego, New York, Boston, etc) have asked me about it. I'm getting ready to print out copies of the flier for e-water since it is so informative to give to anyone that asks about it.
