I live in New Orleans so here's an update. Sugar Bowl will be tomorrow, but at 3pm CST instead of 7:45pm.
The stanchions that normally block Bourbon St and prevent any traffic from getting on the street had been removed for repair. (probably painting them up pretty for the Super Bowl in a month). There was a police vehicle blocking the street, but the nutball drove around it on the sidewalk to gain access to Bourbon Street. He got a couple of blocks down the street before crashing, wounding two police officers, then being killed. He had an Isis flag in the truck.
Police etc did sweep Bourbon Street and found a couple of "items" that were detonated on site. They have not said what they found, just that they found a couple of suspicious items that were detonated by bomb disposal units.
An airbnb that was apparently rented by the nut was also set on fire. Don't know if they found anything there. So far, 15 people have been killed, 25 or so injured.
Just total craziness.
