I don't know why authorities feel the need to restrict someone elses fun. I can understand it in the event someone might get injured, so for their own protection, but in this case, I don't see the need.
Keep in mind I will be in Miami on the 4th for Super Bowl Sunday. Of course I will be on a cruise ship setting sail for the Caribbean, but that is just samantics...
I do plan to stop by some super bowl festivities and enjoy myself though. I might ask some fans what they think of the no tailgating rule.
