In my chosen career path, I have worked at a large number of political events, particularly campaign events. I've been on staff for about a dozen Presidential campaign events.

The flags are huge, often as large as 30' wide. Keeping it from touching the ground is incredibly difficult, but most people respect that tradition. For storage, the flags aren't folded into a pretty triangle, as smaller flags are. They're usually transported in a large bag or rolling hamper, and pulling it out of the bag and unrolling it to hang it can be hard when the flag weighs 60-80lbs. All that being said, I've NEVER seen one laid out like that before being hung. That's just being lazy.
