AT&T Wifi at Grant Part for Chicago Blues Fest!

So I'm currently the Chicago Blues Fest on my iTouch. I noticed that the park is heated up with a blanket of wifi. The only problem is that the coverage isn't the best. Right now I am in the main park and I am getting full bars and achieving a great 1.5 Mbps!

It's nice that AT&T provides this in Grant Park. I just wish they did a better job heating up the entire park...
