Severely slowing people trying to get out of Houston via the airport.
And:
Kids playing on the highway areas as their parents sit in traffic (keep in mind the normal travel time between Galveston and Houston is 40-45 minutes)

Kim Phan, 31, of Houston, is heading for Phoenix to stay with family. She said she entered the freeway five hours ago and has driven less than 20 miles.
"It was moving for awhile but now we're just sitting here," she said.
Children played in the grassy area near the freeway as their parents tried to get their stalled cars moving again. Dogs riding in the back of pickups looked like they were wilting in the sun.
