WiFi in the Superdome
I wasn't at the Super Bowl but the WiFi has been very good for me at the bottom of the plaza this whole season since the offseason upgrades.
It used to be rather poor or spotty at best but after these most recent renovations I noticed a much better experience. Only thing I noticed is every now and then when I'd put the phone away for a few minutes then pull it back out that sometimes I'd have to manually reconnect to the network but other than that no issues.
Hell, the game against the Raiders at the end of the season was so bad I started watching a stream of the Colts-Giants game instead and the connection was solid.
