Older facility. The building that my Delta flight outbound was leaving from had 2 X-Ray machines, so going through security was a bit slower but efficient. Walkways are narrow so walking through is easily congested and worse when people are waiting at gates. They seem to stand in the walkway.
There was someone who went through security and left a black rolling bag. There was an announcement over the PA and a TSA agent walking through the gates announcing the description of the bag to find its owner. Nice to see the attempt to get the bag back to its owner.
