Tampa WAS HOTT!!! And I live in Lakeland which is just 30 min away so I know what Florida heat & humidity is like, but damnit it was HOTT!!!! I'm so glad I was GA in Atlanta, but not in Tampa. I couldn't imagine being down there in the circle with that heat.
As for the energy throughout the crowd, it was tremendous! Wow....72,000 + were fired up for U2 and that only made what was already a fantastic concert that much better! The only downside for me, I don't know exactly when I'll get to see U2 again.
