The American Flag is NEVER “dipped” for anyone or anything.
I came to a cash box (toll booth) one day and it was near a holiday ... I don't know, Memorial Day, 4th of July .. whatever .. and the attendent had those small American flags on the pike.
The flag at the end prompted my remark to him that our colors NEVER, under any circumstance, ever dip ... for any reason.
He said he didn't realize the flag dipped when the pike came down.
I came back through there not too long after, and the end flag was gone.
