Let me translate the hours for everyone . . .
If it officially closes at 5PM, many dealers start packing up at 3PM and a fair percentage are MIA by 4PM. At 5PM exactly, Carole is throwing all attendees out of the building.
If it officially closes at 3PM (Sunday), change the above to 1PM and 2PM. Only difference is that Carole has hit the road at 3PM and doesn't care if you hang around later than that.
